Jeep Wrangler YJ - Fuel gauge problems? Details and demo's included.  

I used to carry a pencil with big erasor when I was a m60a1 tank driver in the usmc...thats how we kept our intercom working, we had to clean all the connectors every couple days. This is the best jeep yj gauge video on youtube for sure...I’m doing this to mine soon, thanks for the info.

A seven year old video just helped solve a problem for me and my throat. I love this guy and utube!

Tabasco sauce works really well for corrosion as well. Same idea as the Louisiana hot sauce, I've been using it for years to break rusty nuts and bolts free...

You are an awesome teacher!

Thanks a million for this awesome video! Just what I needed!

One of the best videos on this subject.

Fantastic video !!!! you just made me realized many crazy things about my YJ 93, thank you so much for this great information !!!!! from Miami Beach

Thanks for the info man! Your video's help me often. I also have a 91 YJ 4 banger. Its funny how we all have the same issues

I'd like to add this as well. Since a sending unit is about $87.00. You can also try cleaning the metal contacts inside the unit as well. We just took out the sender in a 1987 wrangler and leaned it with brasso. Then rinsed with lacquer thinner. When measured in ohms it is now reading correctly. The initial problem was a bouncing fuel gauge needle. All is good and saved a few bucks. Thanks for your tutorial, it was a great help!

Great job, Expertism.

I just bought an 87 Jeep YJ,and your vids are my go to source for diy guides ...you are awesome. Thanks for taking time to film and upload these, keep it up brother!

Great video. I am glad I came across it. I have the same problem in my Jeep. The fuel pump was replaced so the gauge is working sometimes. But you cleaning the contacts on the instrument cluster and seeing the end of your video where you took the plastic "tub" the pump sits in out is where I am looking next. Thanks. Keep adding more Jeep videos!!

Thanks a ton for doing this! Just finished dropping the tank on my '93, and ripped out the tray (gas gauge didn't go below 1/2 tank) and the vent tube. This was a HUGE help. Please keep them coming!

I'm putting new tank in and was worried about needing that thing. I rebuilt my original fuel pump to fit the new tank. This is just good info to know we don't need the extra junk.

Thank you so much I love your videos! Just got my self a 1993yj and fuel gage was broke, stopping at 1/2 tank. the floater was getting stuck on the cup because it was warped. Had to drop the tank to get to the cup but I took it out put it back together and fuel gage works great now! Also did 15 to 20 gallon tank mod while I had it out thanks to you!!! You make great videos !

Great demonstration. You are super helpful... Thank you. I watched your other video about cleaning the gauge cluster !!! That may be my problem. I fill the tank, then it shows empty. So, Ive been using the trip odometer to keep track. That as you know, sucks, so Im gonna take gauge cluster off now and so if thats the trouble.. THANK YOU, THANK YOU !!!!!

Fantastic & educational video ! Thank You !

Brilliant! Thank you!

I replaced the fuel sender and corrected my gauge, but did NOT know about the tub! I will be going back in to get that tub out! Thanks for that. When pulling the sender unit it is recommended to replace the gasket which I did.

Thanks man! Super helpful

Hey Man, Great Video, My Gas Gauge didnt work and after I watched Your Video I went out and found the problem and got mine working. Thanks..

Thanks for doing this video... I just picked up a 91 YJ and of course, the gauges don't work a lick. Now I know exactly what to do about it and in what order. Outstanding!

Great vid boss

love your videos thank u jeep on

Great vidio. Glad I found it and thanks. I have a 87 YJ. I have a gas gauge that shows quarter full when tank is empty, could be the float thats hanging up on the yellow tray as you showed on the vidio and a great job on the gauges.

trying this this summer !!

awesome video thanks man and great idea for the access hatch.. ive dropped my tank 4 times and wish I had thought of that lol

Great video...just got a '93 YJ handed down to me. Needs a ton of work. A little hint for you. In the Army we used pencil erasers to clean all of our contacts on our comms connections works great. Just have to blow off all the damn eraser shavings when done.

i ordered a new fuel gauge cause i broke pin trying to tweak indicator when full. .I ran out with 1/4 tank showing.Now i know real issue.Thanks for the video.Ill see where gauge sits when i install new one.If it doesn't sit right ill have to drop tank

DEFINITELY well explained! All I really looked to find out is that when the tank is full the resistance is HIGHER and when the resistance is zero it sends the gauge a signal which is empty. The plastic piece is most likely my problem. Dummass me filled the damn tank up last night and so I have a full tank to deal with or wait till I run some out. I aint into the siphoning thing any more....... My tank always reads empty....I'm betting the plastic tub is holding the float down.......frikin one thing after another......What I get for buying an old YJ....92......Runs good but already had to change tires (didn't match...BIG no no with 4x4) the high beams shorted out completely....going down the road in black night time where there are tons of critters.....turned out to be the driving lamps they installed and didn't hook up right and shorted out....got a leak on the output shaft of the transfer case.......SHIT! They bent that putting one in it and didn't get another new one......dummasses......and it's got a front end click when turning slightly right......Needs syncro mesh rings....grinds going into gears.......clutch master was wiped out......the hits just keep coming. Paid too much for it too......$5k. I probably could have bought a real nice one for what I'm going to have in this one......!!!!! Sellers are liars! My own damn fault

I think this might be what is wrong with my fuel gauge.. I had a brand new sending unit and all installed. When I got stuck in the Nashville area. Two months later I hit a pothole here in Knoxville and my gas gauge shot to empty. A guy did the gauge test and it worked. I bet it is that little box/tray

What would be the best way to replace engine motor mounts

Love your down to earth videos. Glad i watched to the very end as my problem is my gauge goes up to full but doesn’t go below half full. Quick question, when you pulled the two hoses off the fuel pump why didn’t you mark them to know how they go back on?

Hey Chuck how you doing buddy, hopefully some warm weather is heading your way, I'm in PA so I know the cold just wanted to ask you bud heard you say about replacing your fuel lines from top of sending unit I'm about to do a fuel pump in my 92 yj, you got any idea what length those lines are and size? And I probably should replace clamps too? Fuel injection clamps? Thanks bud always great to talk to you.. got a ton of projects for this yj coming up.. I always like second opinions

Awesome! Very well explained. I understood everything you said and there was no problem with your videography. You should teach classes for women. Now I can't wait to get my jeep back and fix the gauges. I am having the exact same issues.

THX a lot for this awesome vid!!!! I've the same issue and I'll try to fix it. One question: could you please tell me the location where i have to cut the hole in the frame to get to the fuel pump? thank you so much and have a great time! alex from austria 🤙

I just put a new oil presure sensor in the 94 wrangler. It now shows max pressure even though there are no leaks, no trouble and it is connenected properly. I know there are 2 types of sensors, one for a gauge, and one for an idiot light.. I have the correct one but it doesnt work. Should

Check out the Jeep Wrangler fuel gauge fix video that I have had several requests to make. Gotta YJ with gauge issues? Maybe I can help. I caught as much detail as possible to help assure that this video would help you fix your gauges. Check it out ...

Just watched the video...awesome. I was wondering what the point of the yellow tray is at bottom of tank and any downfalls to removing it?

Does anyone know if you can buy just that yellow tub new?

I just had a new fuel sending unit installed. Now with a full tank of fuel the fuel gage needle pegs out past full mark. Can the stops be for the float be adjusted?

Great video. Thank you for doing it. My fuel gauge always reads full. Any idea what the cause would be? Hoping to clean the cluster this week and see if that helps.

Can you tell me about your seats? My 93 YJ has some ass chewing pis seats and I really want to replace them. Being in Texas, I only run a bikini top so I need weather resistance. Thanks guy! Just found your channel and love it.

Okay so, about a week ago I filled my 95 yj up completely for the first time since I bought it, have had it for about 10 months now. Before this my gas gauge was working just fine but I noticed a few days after that my needle won't budge and is stuck slightly above full. I would assume the arm in the tank has somehow gotten stuck, but I figure I should ask for other opinions on this because I am by no means a mechanic.

Hey man, I’ve been struggling with my 95’ 2.5L. Installed a fuel sending unit from Amazon lasted a year surprisingly. Figured the pump quit so I replaced it with a delphi pump I had sitting in my toolbox, it didn’t work. So I got an import direct fuel pump, still didn’t come on with the key but will work when directly attached to the battery. I have power all the way to the pump, I have a good ground. I’ve also replaced the plug on both sides of the fuel sending unit due to the original being worn out. I’ve checked my relays by putting them in the spot for my horn and bumping the horn, all of them worked. Any help is appreciated!

Pencil eraser or a pink eraser are good for cleaning contacts. I prefer that over razor blades. Then a good cleaning with a contact cleaner then dielectric grease

Thanks for your video - any issues when doing sharp long turns with the plastic tub removed from the tank? I know it's made to hold fuel in the center for the pick up of the pump to prevent from starving. Got the tank out and debating whether to use either heat from a blow dryer to melt it back straight, or to bend the rod to make it avoid the tub.

Great video. I've owned my '93 for 20 years and I always ran out of gas at a little over a quarter tank. Learned to live with but still hated it. Had an expensive mechanic change the sending unit but still no improvement. Now I suspect the little tray. My problem is I don't think it's that easy to drop the 20 gal. tank I have. Any suggestions?

have 89 yj ,gas gage works but needle bounces around ( as tank empires ) while driving & is almost empty between 1/4 & 1/2 , would that little yellow tray be my problem for both cases . like ur videos has helped for other problems .

I just had a brilliant idea , making a low fuel light

Hey great video but I have a bad fuel pump but I really don't want to drop the tank do u think it is a good idea to cut the hole in the back like yours that is so smart and easy

I just bought a 1987 Yj and I'm wondering how you can do the electrical for the back lights?

Could you please let me know the dimensions and location of the access panel. That's one sweet mod. (That I hadn't thought of) 91 YJ's Rock! at least mine does. Thanks.

Can u use ketchup as well or Brass cleaner ( Brasso) TIA. 👊🏼 bought a 94 brand new and would never get rid of had just built a custom bike and told the wife I need another project! She say what about the Yj ?? Now I have a new project ! Complete Jeep everything there new top tires starter master cylinder new transmission ! .. so I’m thinking tearing down and redoing ! Need fuel pump . 325,000 miles on her and runs left me new 4.0 high output 6cyl….

I know this is an old video and I hope you will reply as I have my 87 YJ fuel tank sitting on a table testing the gauge float as Im typing.....question....@ 41.06 in video the fuel gauge slams to full without the sending unit attached when you turn the key to on......should mine be doing that as well?....when my switch turns it bumps up a tiny bit but thats all, so the whole tying the wire together doesn't do anything either.....thought was my sending unit but appears not to be......any help will be appreciated...love your videos, you have already helped me tremendously!

Looks like you have no doors on but still have mirrors on, how is that since the mirrors are mounted on the door hinges? Could you make a video one day with just an overview of the jeep, interior and exterior, Ive seen so many tech videos and im kinda getting curious on what the jeep actually looks like. thx

im haven issuse with my speedo . already changed my tran sencor witsh was needed but is still now working . you have any thing for that

I recently changed my gas tank on my 93 yj. Before I put the new tank in my gas gauge worked perfectly. The new tank I purchased did not include the little plastic tray to hold fuel like the stock one had. The problem I'm having is now my gas gauge is just stuck on full(even after me driving several miles) the gas gauge won't move. I transferred the entire fuel pump and sending unit from the stock tank to the new tank. Any ideas on what's wrong? I'm going to try and drop the tank again this weekend and pull the system off and play with the float up and down like you did to see if it's working. Any ideas? Thanks.

Did you have to modify your hanger for that Bosch fuel pump?

Hey is there any specific way the fuel pump needs to be placed back in to the tank cause i had to remove it to replace the gasket and drove it for 2 days just fine then the fuel pump went out idk know if it was the way i put it back in or not

on my 91 yj my gauge does what ever it wants it can say empty of full and over full even any hints????

Citric acid and water works well on copper

Okay so in my 95 jeep wrangler yj my gauge works, but it goes really slow, what should i do?

the vinegar and salt in hot sauce is what cleans

What kind of grease is that?

Why’s your dash smell like hot sauce bro? -don’t worry about it 😂

Have you encountered problems replacing the clutch assembly?

they should have made that little tub wider so if it was prone to warp nothing would hang up and give a false reading

The vinegar content is what done it

in this casa does any hot sauce work or that one got a special ingredient lol

Ive even seen some people rip that little tub right out but the reason its there is probably for angle and such when wheeling like u say..Good call..Its just a shitty design thats all!!

wouldn't vinegar work better since the vinegar in the hot sauce is probably whats doing the cleaning

lol called his pliers big ole reach and get em pliers.

You gotta put your hand behind the thing you are trying to focus on like the "beauty-tubers" do lol
