Only video I found that addresses this problem. Thank you!

I really hope you make it as a full time youtuber!!! I love how easy you are to watch and your content is VERY easy to follow. good luck Charles and keep up the awesome content.

This happened to me last week. I was worried about having to diagnose the problem for about a week until I tried a different pump at that same gas station. Filled my tank up without any problem. Stations have faulty equipment too.

If you are always filling up to automatic pump cut-off, a flooded charcoal canister would be my first guess. Simple fix: don't fill past ~90% full for a while.

Gotta love my '68 pickup truck. 👍👍 Two barrel carb and no emission, testing, passing or inspections. But it does get 8mpg on a good day. 😒

This is a very common problem with Dodge/Chrysler/Jeep vehicles. It is pretty easy to find forums of Jeep owners that have this issue. Replacing all these parts won't necessarily fix the issue, as many jeep owners report. It's likely a manufacturer/design issue for that era of vehicles

Chrysler has an issue with the roll over check valves sticking open. Jeeps has a huge problem with this. They recommend replacing the tank because the check valve is "part of" the tank. I have been able to repair them without doing the tank. Saves people money!

My 98 Nissan pumps slowly and does this if you try to pump fast, but I already did all the emissions stuff. I did notice that in most other towns with different sea level heights it will pump completely fine.

This is literally happening to my truck right now! It has been for the past 3 months and nobody has been able to diagnose it until now!

You just became a hell of a lot cooler, in my eyes, by helping out the TSP community! Thanks dude. :)

I have this exact same problem on my 2008 Chrysler Town and County. It spews even more than in this video and slowing the rate of fill can get me past it, but it will literally take me 15 minutes to fill the 20 gallon tank! Not only is this time consuming, but I cannot use the lowest lock setting on the gas nozzle handle, so I have to baby it and tend to it the whole time it is being filled. This issue came up suddenly and happens about 90% of the time now. Also just a few weeks ago my check engine light came on and the code was P 0456 (ECM detects a very small leak in the evaporative system). I haven't gotten under the vehicle to diagnose, yet, but this video is a great start for what is probably going to be a lengthy process. Thanks for the tips. Very much appreciated.

had a very similar Dodge Ram issue before and ended up being a pinched shut vapor line on the top of the tank not being ran back through its depressed channel and then made worst by the seriously over torqued hanger bolts deforming the tank.

this happens to me too smh & today the fuel spilled all up my arm🤦🏽‍♀️

Never ever had this problem with any of my cars ever... but yet again I live in Europe and it's either pay the mortgage or fill up the tank 😂😂😂

Many Libertys have that problem. Source: My 2005 Jeep Liberty

A lot of these newer style pumps are known to have issues. I have a diesel that has no evap system, no vents, literally like pouring into an open tank. Diesel pumps usually won't shut off until it's flowing out the spout. I used to own a '66 Ford Galaxie with the same style tank, the gas pumps did the same thing. Didn't matter if it was held wide open, or going as slow as could be.

Have same problem with my 07 Jeep Liberty. Supposed to be a common and according to the forum. Jeep is aware and can't or won't fix it. Some guys have replaced the tank and inlet only to spend a fortune and have the same problem. Only thing that works for me is to fill as slow as you can. Hope you have better luck!

I bought a truck off my friend. I went to go put gas in and within $2 going into the tank it turned the handle off and sprayed gas out like in the video. I had to pump $1 at a time for $50 😅 my tank was almost empty (was sitting on the red line) when I opened the tank a bunch of air came rushing out so I definitely have a vapor lock somewhere and this video is definitely going to help me

I have a 2009 problem. Changed all the canisters. It spills out i slowly gas up. Been doing that since 85,000 miles on it. I still have the it has 250,000 still have the same problem. I think there has to be something in relation to the gas tank. Well i keep driving it. It has other problems as well. It starts when it wants to. But whatever its my 2nd car my work car.

Oh wow, I've never seen that happen before. Great video as always Charles!🤙🏽

My solution is to fill up the tank to about 5 gallons before full. Then stop. Let it sit for 30 seconds. Fill it up slowly for 2 gallons, stop, sit 30 seconds, 2 gallons, 30 seconds, repeat until full. I've used this a few times with no gas at all coming back out. I've worked at a gas station in NJ (No self serve state) and all of these spewing out gas problems is a real headache.

Hey Charles I had one that had a pinched vent hose. Its a pretty big hose and easy to see. It runs right along the filler neck.

Thanks yeezus! This is exactly what happened to me. Good stuff :)

From looking at his video he is using the second notch on the pump handle. I recommend using the first. It will fill slower, however it will be less likely to overflow. My wife had an 06 Pontiac Vibe with this problem. Using the slower setting solved the issue.

Interesting that I have this exact same year make and model of truck and have the exact same issue. I have not read through all of the comments yet, but it will be interesting to see what the issue was.

it's a recall on Dodge's the pressure relief on the filler is faulty happens to my moms Durango all the time take it to the dealer and have that recall fixed

I just had a new fuel tank put into a 2004 Hyundai Santa Fe, and it's only been filled twice since then. Both times, it overflowed...looks like the same amount in this video. It never did that with the other tank, or in our Buick either. I can't help but feel it's related, I'm just hoping it's not actually a valve within the tank. It has a warranty, but I don't want to pay for another repair. I'm already up to 1400 in this vehicle this summer. Some people tell me to get rid of it now, but I've only had it since June. My brother left it to me before he passed away and I guess I'm not ready to let go of it. It actually ran better before the mechanic started working on it. He suggested a new timing belt...then screwed that up and " fixed " it to make it better, but it's still not running as well as it did before the timing belt change. It still bucks once in awhile and the check engine light keeps coming on. Two other things it didn't do before it's initial " checkup " with the shop.

I have the same problem. I've been figuring how much gas i need to fill up and take it off of autofill a gallon before full and slowly pump to full. My theory is that the nozzle shape doesn't fit down the filter neck far enough.

Something I noticed: This only occurs at certain pumps. For me the only pumps I have tested that this doesn't happen are the Shell and QuikTrip gas stations. Murphy, Costco, Valero and 7-Eleven seems to make it spew though.

I replaced my evap can and it still does this. Will look at the lines again. Add too it randomly dies after refueling. No check engine light or codes...

I have a Dodge Ram 2008. There was a service recall on my truck a few months ago and they replaced a pressure valve for free.

This is what my Honda CR-V is doing but it doesn’t end. Like I could go out there right now, take off gas cap and it would start spewing out. It’s in the shop right now. $119 JUST to diagnose it. One thing I’ve noticed is no flapper valve door (little silver flap you know). Not sure if that’s cause.

2015 Mazda 5 does the same thing. I’ll have to follow those steps. I’ve not tired yet because like Charles said it’s not so easy on a small car. Need to figure it out though because my daughter is going to have to start filling it up herself…

many vehicles today especially pickups have a hose in hose venting system which allows tank vapor to exit the tank neck as you fill the tank. It will regurgitate if you over fill the tank.

You need to tell someone not to smoke around gasoline? No, no no.... survival of the fittest.

My 2001 f350 7.3L has this problem and the fuel from the backup tank is extremely slow to fill up with I flip switch valve

I have a 2008 Ram 1500 that did exactly the same thing.

In the past i worked in a gas station and saw this on a regular basis. one thing that fixed some of the the customers " Before you activate the pump put the handle in the tank and try to use it a few times" sometimes when a previous customer tops off the end up flooding the censer or check valve trying to get up to that full dollar amount. this worked 16 years ago so take that with a grain of salt.

I used to work at a gas station and normally when I ran into vehicle with that issue, I monitor it to hear when its coming up then I unclick the nozzle quickly and do the rest of the filling process slow. it worked, but as a side mechanic things I've figured which could cause that issue are air in the fuel system, pinched lines, clogged lines especially the return lines and a dented tank.

My 99 Nissan maxima ran beautifully til last week. I took it to Murphys and put 91 octane in, which it calls for. I’ve alternated between 87 and 91 and never had a problem, and believe previous owners did the same. This time however, when I opened the gas cap, the sound of vapor or air exiting came out and then I filled with the 91 and fuel came out when I was done. Since then I’ve had some knocking. I’m not sure if there’s a clog or I should switch octane types…. HELP

It's a Chrysler. Were we expecting anything less from them?

Thanks and yep your right I've been filling the tank to get the even amount

I have a 2010 Jeep Liberty Sport, and Limited edition, and it too has same issue, unfortunately like he said everywhere I go, I have to purchase a new Full gas tank of 1k Dollars..For the gas tank it self, I learned to go to a quarter of a tank and put..30 in it, and call it a day and leave it to the next owners..issue. I can live with it.

Fuel tank sounds like my fuel pump. Whole thing has to be replaced when a valve goes bad.

Theres a TSB for this issue, on some Chrysler vehicles. Calls to replace the entire fuel tank.

You can actually test all of this with a smoke machine and a vacuum gauge. Likely a vent valve problem. Check for codes for say a vent valve problem

This happens with my ‘05 f250 every time I put gas in it. It backs up as soon as the filler tube is full which leads me to believe there is some sort of filter screen or baffle that’s restricting flow. I also smell fuel all the time.😭

MOE . i had a 1982 RAM 3/4 ton. the tube from the filler neck top ran all most horizontal to the tank. the best fix i found was setting the nozzle at the top or bottom of the tube. cant remember which. and dont stick the nozzle to far in.

yeah I say he just has a major problem with the vent being clogged and the air can't go nowhere so that's why it does that and doesn't matter when he fills up it still does same thing need figure what is clogging up or what is or where at that should Fix the problem can always smoke test and figure if it's clogged anywhere or if it is

My Audi B7 A4 would stop about 15 times while I was fueling. Start it up and a couple seconds later auto stop. Turns out the charcoal canister was completely clogged up. Previous owner probably kept overfilling. Could easily be a charcoal canister.

seams like a vent problem forcing fuel back up the tube my truck would do it only when i filled it from e it would make the pump kick off as well

So I had code p045 and said fuel neck ..clean it n replace the vapor canister. Still will not gas up. Check the the lines for kinks.

Wouldn't this issue fall under the emissions warranty? They are typically 8 year / 80,000 miles. I'm asking since it could be an EVAP issue.

charcoal canister is bad or the evap solenoid valve is stuck closed

have a geo the vent is at top of filler . station nozzle rubber disc blocks vent if u turnnozzle upside down don't spill also some pumps fill too fast varies at same station from pump to pump.

When I try and put fuel in the charcoal canister takes it spills it on the ground,Why is fuel going to charcoal canister?

I find I get this issue on my jeep, beginning of the summer it's fine, after being on several high angles it starts puking when I fill it, unless the last 5L or so is filled dead slow. I always figured it was the high angles produced by being off road that fills the evap canister. After parking it all winter it's usually fine for a bit.

my 2005 Dodge Durango Limited did the same thing. My local Dodge dealer changed the vent check valve and a clogged hose. Didn't cost me anything they did it under an extended warranty/ TSB.

Idiot at autozone tried telling me I'm not supposed to force fuel had no clue what I meant . THIS is exactly my issue. Thank u sir. Let me go educate this dude.

We have older Rams spewing fuel back at people, today I diagnosed a brand new 2020 Ram with an EVAP leak. Plastic EVAP nozzle snapped off the fuel pump leaving some of it still in the hose. How? No idea as all these components sit between the top of the fuel tank under the bed. FCA makes some pretty shit vehicles.

If the problem is severe enough to cause a spew that bad already, i wouldn't even try just filling it slowly. That indicates that there's a problem, and letting said problem sit and happen can cause more damage in the long run. I always fill on the slower fuel fill nozzle lock position because it stirs just a little less fuel and I can cram just that extra little bit that's not returned to the station's evap system as vapor. At least, that's my mental process. I've found that i can fill the tank on a couple of bucks less on average doing it that way than going full bore all the time. Either way, his paint job is probably suffering. I feel for him. tank replacements aren't fun. I wish him the best.

Hey Conrad, I have a 2006 Jeep Liberty, and sometime it the gas appears to overflow, but I mostly fill the car half tank. I see this is becoming a problem and I am not sure if your hit on it. I would like to know if you have any advice.

Filling the tank slower is the best idea and I'll take it a little farther. Listen and feel the pump. You can hear and feel when the pump is about to shut off. One of my pet peeves is when people lock the pump and walk away or sit back down in the car.

do you have a vido on how how to fix this issue ?

My 06 Ford Focus does this every time I fill up. No matter how slow I pump it, when it’s full, it shoots out. Gonna crawl under it one day and figure it out.

while you are filling you are causing, what amounts to, a bow wave of fuel in the tank due to the force of that fuel coming out of the nozzle physically pushing the fuel to the far side of the tank. While still filling there's no problem, but once you shut offthat fuel that was being forced over there *points* no longer has the force pushing it so it comes back to level off. Unfortunately, when it gets to the filler neck you have an inch high x the width of the tank worth of fuel and you get the "tidal wave effect" where, because of the sudden restriction, the velocity of the fuel increases in that small space and....sploosh, all over your nice suede shoes. I learned that one in my first year when, as a first year apprentice and saturday morning jobs would be grease the trucks, check the wheel nut torques on every truck with a 5 feet long, solid torque wrench! ( easy now, but as a weedy 17 year old it took its toll) and i would top the tanks of all the trucks in the yard and end up with a blue puddle in front of the diesel pumps until a second year apprentice told me to stop pumping when the sound changed note and then pump small amount until full.I hated saturday morning jobs at that stage...the only good thing to come out of it was i got to drive some very cool tackle and that bit i loved

07 Ram was recalled for this mine was one of them. It always spewed, before the recall. They replaced the filler neck.

My 2007 Durango has done this for years. I just know how much gas my tank takes to fill at various levels and never let it completely fill to shut off the station pump.

my 82 k10 doesn't vent fast enough for the new pumps so I just pump slower and it dose just fine tho it would help if I relocated the vent from the side to the top of the metal piece of my filler neck so my vent tube doesn't fill with gas

Had the same problem with my Durango. They ended up changing the entire filling tube. Something they knew was defective.

Thanks for watching everyone! I also recommend you check out The Survival Podcast. Even if you think that it's not your thing. I started listening years and years ago. I can tell you 100% for sure, if not for the community at TSP, there would be no Humble Mechanic show.

My 2010 Ram 1500 does this too. Such a pain.

My 2005 Chevrolet Colorado has this gas issue. I need help.

I have an 08 wrangler and this fuel spray is crazy, I have learned to catch it b4 it happens,but it happens every fuel up. I just have to catch it in time or else it comes out forcefully like this guys. Just today I was filling fast and got distracted, not a pretty site. I want to just fix it , but don't want to just throw parts at it. for now though I just listen and stop b4 the auto shut off, check my gauge then fill really slow till my gauges is touching full.

I have a 2008 Chrysler Town and Country. It spews gas way more than in your video. :-( I've been putting up with it for a couple of years now. It takes about 15 minutes to put 20 gallons in the van. I can put in about a half gallon at a time. Then I have to wait ten seconds for it to settle. If I don't, there is geyser of gas that shoots out. Pretty sure what you have said is my issue. Need to check the evap system. Also, I get an error code on my dash that says "gascap" every so often. I know gas cap is sealing fine, but there must be some kind of pressure sensor triggering this. Need to get to this soon. Very frustrating.

also I'd bet filling up more frequently would help, can only imagine going from an empty tank to full would spit back more fuel than 3/4 to full would.

Older cars tend to spit fuel, my 55 does. But the reason it does is because modern fuels tend to get super foamy when ajitated, even worse if the tank is empty and warm as well as fuel with Ethanol tend to vaporize quickly, cold gas in the ground going into a hot tank. I don't run into the problem with non-Ethanol fuel and just fill my tank really slow or surge fill , go fast then go slow fast then slow, listen to the sound of the fuel going in, if you can hear it in the fuel neck slow down. My assumption is that there is foamy build up in the tank that causes liquid fuel to stay trapped in the fuel neck, once the pump shuts off the trapped fuel has no choice but to be spit back out.

I have 2 days going on 3. I dropped the tank twice. Blew air through every line replaced charcoal canister vent valve purge valve and blew air through the line to the front of the engine of course disconnected and blew air through the fill tubes and return vapor tubes and everything is clear but every time I pump gas it spills a lot of fuel, my next thought is that tank might be issue I even knocked off the door that lets the glass in thinking it was the problem

I have a 2006 ml350 and ended I turn it on, I have approx 5 SECONDS TO SWITCH IT INTO GEAR, otherwise the gear locks up in Park and I have to turn my car off and then back on. The Mercedes mechanic didn't know

In all my years of working on cars I have never seen a pukey fuel tank. Usually the vent valve plugs up and you just can't properly fill. Takes 3 weeks to fill the tank 😖😤

Man I'd be pissed if this happened to me. Thanks for the knowledge as always 👍

This is still going on with my Nissan Titan every time I go to put gas , I switched the gas pump and the vent valve and has fixed nothing

I have this problem with my Jeep Patriot. It's the rollover valve in the tank and it sticks. This one valve causes all sorts of problems depending on which way it sticks. In one direction, it closes the air vent causing fuel fill issues like in this video. If it sticks the other way, it causes an engine stalling issue right after filling the tank as the raw fuel gets sucked through the canister purge valve. Rather than spend $400 on a new tank, I'm just going to add a new bulk head fitting to the tank and Tee it into the existing filler neck vent line. I've already added a catch can to the line between the canister purge and the engine to stop the stalling. And yes, I am aware this bypasses the "rollover" function, but if the thing is sticking open anyway due to Chryslers poor design, it's already broken anyway.

My 2009 prius just started doing this. It has a bladder tank. No release. What do I do???????

My 11’ ram does same thing

A slow rate of filling don't help. It takes about 30 minutes to fill my 2004 Dodge Ram 1500 with 5.7. As soon as you start pumping it cuts the pump off. It's a recall but Dodge doesn't consider it an official recall. It is a factory defect on Dodge just like the water rail under the windshield. Park your Dodge with the nose upwards & the water fills your floor board. So if it rains park with the nose downward. I replace the heather core thinking it was that but it still does it. Same here. It's a recall but Dodge doesn't consider it an official recall. Dodge SUCKS.I will never buy another 1.

woulnt not filling to the top not cause this

I had this problem with a hyundai Santa fe at the dealership and there was a kink in a hose. The only way to fix it was a new tank because the hose didn't come by itself.

I just overfilled my car today. Most of the gas is inside the tank, but I cleaned the gas that got spilled. Is it gonna be bad to my car?

my Hyundai's charcoal canister broke up inside causing the charcoal to plug a vent hose. it didn't burp fuel but took forever to fill. love the vids my fellow UTI alumni.

Is it bad for a vehicle if some gas comes out of the tank like that one did but not as much

I had the same problem in my 2008 Dodge ram 1500. After $2500 later the dealership found what the problem was. it was the seal where the filler neck gas tank meet. so I had to replace the gas tank. after they install the new gas tank I haven't had any problems

My 2000 Silverado 1500 wouldn’t take fuel for nothing. I disconnect the breather hose from the canister and try blow air through it and fuel just gushing out of the filler. It hush out just like the truck in the video. Please help!

i had few chrysler gas tank check valve stuck and a bad gauge "customer had his gauge at 1/4 tank and he/she was complaining she can only put few liters and it will spew back. turn out the tank is so full"

Hello charles, my name is Mike and my question is; i have a 2000 VW Golf it burns too much oil. I've looked into it and i guess there is oil going past the pcv and im assumeing im burning all that oil. In a week and a half i will burn up to 1QT of oil don't matter if is good oil or not. I'm useing 10w30 and my car is a 2.0 aeg. How can i stop the oil consumption, please let me know. This is driving me crazy. Thank you.

I’m having a similar problem with my 1998 Dodge Dakota 3.9 V6. I was filling up gas and was giving it a little extra. Then before I know it, gas is pouring out underneath my truck. Not from the fill spot. Literally under the truck. Any ideas before I end up pulling the bed off to take a closer look?

Thank you for the video! I have a question. What is the best way to ask? I was hoping you could give us some information on diesel gate. How the fix for the 2015 is working and any information on earlier years fix. I have a 2013 TDI Passat.

I had a worse situation than this, it was a hot day like 42 or something, i was using my hiace 2006 to travel between jobs, and while trying to put petrol into my van as soon as i oppened the tank cap, it sucked alot of air then it squirted gasoline out like a hose, it sprayed all over me i ended up in hospital, so what I'm trying to understand is what has happened here, where is the issue ?

well if you own a 73-87 chevy truck your used to this... lol the filler neck is at a wierd angle and all of them do this, some screw up in the design
