Building A Custom Fuel Tank for the - Mini 4WD Trophy Truck Project - Part 15 

10x14x18=2520cubic inches divided by 231 =10.901 gallons. - thickness of the metal and everything in there. It’s looking awesome

you def should have a fan going/more ventilation when welding!

man how chris edits these videos with the lofi and the machining its soooo satisfying to look and listen to. keep it up chris love your videos

Great project. On the vent…should probably have a check valve and rollover loop to keep fuel from leaking if you flip or roll.

maybe add a shielding so the chain can't destroy your fuel tank in case it fails

Hey Chris, Keep up the great work! You really need to use an "Ball Check Valve " for you tank. They do make an "Ball-Check" vent for race car tanks that would work great! There is an check ball that seals the vent when it is upside down. Run a fuel line to an breather up higher on the frame. Summit and Speedway motors both make them. Love your work!

Hey chris, you should install a pvc valve for venting!! Like chevy uses on their V8 motor! I did it on a circle track car rolled it on its top no leaks at all the vent you have will let gas put!! Your workmanship is awesome!!

With the angle the tank is installed, the fill port is higher than the vent port. The vent baffle is a good idea, but if you fill to the top you will cover the vent. Move it to the aft corner.

From a Welder for 35 yrs, your welding is looking pretty awesome WTG

You are right about your Aluminum welding, I follow your videos religiously to get ideas for my Electric 4WD UTV car, and I must say that you're becoming a pro at welding Aluminum.

Don't stress, sometimes it takes time. I like what you do. :)

For the fuel vent, you realy should put a check valve on it for safety. That way in case you roll over fuel won't go everywhere. It also fixes your worry about any fuel sloshing out.

If my math is correct the tank should be just shy of 11 gallons but with all the baffles and fuel pump probably more like 10.

I really like the way you made that perfect fuel tank and the tank sensor

Great videos. I think you might want to double check the o-ring depth and width. Hard to tell from the video, but it didn’t look deep and wide enough.

You can say sloshing if you like, but… baffles are installed in tanks to prevent liquid from surging. Love the project.

That's right I was told aluminum welding fumes not good for ya ! Great work 👍☮️

I'm always amused by the amount of gnarly and not-square bricks you use in metal working. And still make it work.

Just a safety note, an oring is probably the best way to seal the gas tank to the sending unit, but I noticed that the groove was much smaller than the oring profile. The oring was outside of the groove. Leaving it this way can lead to the oring being damaged and not sealing. The parker oring handbook can help you find the right one for the groove you have machined already. I can also help you identify the correct size one for your groove if you want some assistance. I really enjoy the content, this is a very cool project!

Awesome build. A quick note for your vent tube. Make sure you put a hose on it that follows the underside of the main whoop all the way down to below the bottom of the tank. This will make sure nothing will come out if you ever have the crazy experience of parking it on it's roof. Expect that to happen and plan for the worst.

FYI it may be in your best interest to install a roll over to you vent to avoid fuel from spilling out.

you can buy a proper vent for the tank that allows vapour out but not liquids. When it slops about, it will pressure itself out that vent unless the fuel level is low

I recommend looking into Ultra4 or SCORE rules and following their guide lines for the fuel tank vent. Routing the rubber hose as they say prevents fuel from spilling in a crash or roll over. Cheap safety.

Great job on the gas tank Chris, your welding skills sure have improved.

I appreciate the attention to detail! The project seems really ambitious at a glance but the amount of effort and thought put into just the fuel sloshing around in the tank is really impressive. Can’t wait to see the final product!

Well your one step closer to having my rock buggy finished & I really appreciate it .

10 gallon tank should last quite a long time

You can use a little check valve on the vent

Use a fuel cell rollover vent. It has a check ball to prevent fuel splashing out of the vent. Plus pigtail line off of the rollover vent to the ground below engine.

Have to agree on the welding looking much better

Amazing best videos Very useful and inspiring.. great Greetings from a traditional Indonesian gold prospector 🇮🇩⚒️⛏️💖🌺👍

I can see why you'd RATHER BE WELDING 🤣because you are very talented at said task.keep it up!

Love the truck looks cool. Only thing I would change is the very back that looks a bit square. Great work.

I have calculated a little less than 40 liters, discounting the volume of the pump and the gauge... good job!!!

Love the gas tank the builds looking sick love watching you work i find it very therapeutic 🥰🥰👍👍

Anyone else click on these videos so fast that you didn't read the title¿? It's just clicking as soon as you recognize the thumbnail style... 👍

Thanks for this video Chris. 👍😁

Your machining and fabrication is so good! I just wish you had a partner or two to really envision and solidify project details and help you work. You would sooooomuch less time redoing things.....

Huge shout out from Algeria i love your videos and i've been a fan for years now !

You are The best welder bud 🎉 allsome work

Your fabrication is top.. love to see you work and with patients .. may be you wanna add a tank guard or a pump shied ! :)

this man is on another level

Hey man just got to say i love your video's, everytime i watch a new one im even more blown away not only by your fab skills and what you can do in that small shed but also by how your brain works (example... with the breather valve and the cover you made to yes as you say stop it sloshing up their. Yes sloshing is correct well where im from anyway. ❤ from the UK 🇬🇧 brother 👊🏼

Allsome work chris.yip I really think that is a allsome Idea for sure 😊👌👍🌟🌟🌟🌟🌟🦇 keep up the allsome work from cruzermans inventions 🦇👍

Because aluminum cracks so easily from stress, you should mount it like a battery. Sitting on rubber & strapped down.

That's awesome free hand

Learning how to weld aluminum is one of those things I still need to do. I think I personally would have went with at least a short neck leading to a vented cap. That vent will be spilling fuel if you go off-road with a full tank. Putting a riser on it to give the fuel a chance to flow back down before making it out might be an easy way to fix that if it becomes an issue.

Nice job with the mill bro.

Hey Chris - speaking of not feeling well and wearing a mask, strongly recommend you get a small water troff below your Plasma table to catch the fine particles of metal instead of it going in the air or all over your shop. This build rocks, man.

Love these vids chris, your builds are inspiring

For second i thought you said "ass tank" while standing at the back of the rig with the gas tank. Gave me a good chuckle

Slosh/sloshing is the movement of fluid side to side in a tank and surge is the movement front to back. It’s part of the training I had to provide to new drivers carrying bulk fluid tanks and tank trailers because that movement can and will affect your drivability as well as stopping performance in ways most don’t realize. With that said it’s not a very big fuel tank but you were still wise to install baffles to reduce fluid movement as much as possible.

Need to do some research on the old Ford Pinto and Maverick, your gas tank placement is a great concern.

Looking great 👍🏻, I just calculated your gallonage and came out to the same as the fellow that comment before aprox 10.9 US gallons

You don't need all those holes in the baffles. A 2" or so D cutout at the bottom of each baffle is enough. The fuel will level itself pretty quickly.

You should put a one way ball check on the vent in case of a roll over. Wouldn’t want to see you get burned.

Love seeing your video notification!

Hello do you mind doing a little video tutorial on your tube notching techniques, ur work fits so perfectly

I just wrote this comment on one of your videos from 6 years ago and have decided to also post it now as the comment is about the difference between the channel then and the channel now. So is relevant to both times but also I really hope you're more likely to see it if I post it in the most recent video. Anyway - >>> Mate, I've been binging on your channel for a couple of weeks and obviously did the normal thing of starting at the most recent videos and working backwards through time. Anyway the difference between today 15th of May 2023 and this video 6 years ago is wider than night and day. There like 2 totally different channels that are presented by 2 different blokes who just happen to look exactly the same. The amount your knowledge of the various areas you deal with, your ability and skill level, are many, many light years different. Whilst you obviously had some natural ability with such work at the beginning and lots of determination to learn and improve whilst you worked, the ability you have now, in the latest videos and how different it is watching you as you practice the various skills, welding, fabrication, lathe turning, machining of any kind, your general mechanical knowledge, skill at working on engines, etc, etc is absolutely massive, like a totally incredible level of difference between every area in the time between the two videos. As I said it's like watching 2 different people and that's just talking about your skill level at the manual, machining, engineering, mechanical, and designing side of things. However the other changes, your presenting, your filming, editing, the look and feel of the videos has changed for the better just as much, if not more. Honestly Bro you should be very, very proud of the channel you now present and run. At how much you've improved and created something of a high level of talent, ability and entertainment. Possibly the biggest difference though, despite all I've already mentioned is how 6 and more years ago, the amount you used to waffle and go over the same topic, sort of getting self conscious and feeling out of place and not knowledgeable enough to really be doing, saying what you're doing or saying, compared to what you're like now. You can see and hear the confidence in both what you're saying and what it is you're doing and the fact you now feel like you have the knowledge, skills and the right to really talk about these things. You no longer feel the need to justify every action, explain every move, decision or comment you make, which you did constantly at that point 6 years ago, in your journey and trust yourself to be saying the right thing. Your knowledge of what to show and what to skim past has improved immeasurably, along with how best to show it, explain it and entertain whilst "teaching" showing how to do something. What works, what doesn't and explaining why it either worked or didn't. Never mind your sense of style, how you present yourself and the videos which has also changed drastically. Mostly because it seems you no longer care what others think or expect and now just do you, having learnt that no matter what you do or don't do there will always be someone who says you're doing it wrong or telling you how it should be done, etc, etc so it's really not worth bothering about as long as most of the people watching are enjoying it and getting something out of it, then you're winning anyway, especially if you're truly enjoying what you're doing. Anyway basically what I trying to say was extremely, extremely, well done and if you keep improving, keep working as hard, keep being as enthusiastic, proud of and truly enjoying what you do and create at the same rate then 6 years from now you can expect many more subscribers and to be hosting, running and being the owner, creator of own one of the top channels in this sector in the RU-vid world of channels. Perhaps you'll even get someone to put your ideas and designs down in CAD or do it yourself and then actually building the exact same thing in the designs and as you thought you were going to be building in the first place and ending up with the actual thing you wanted to create at the start. OK yhea, I know that's possibly pushing the realms of reality a bit too much, despite how much you've already pushed them with how much your channel, your videos and especially you have changed for the absolute better already, here's to another 6 and more years of this channel and you growing. Thanks for the entertainment and knowledge. 😊😅😂👍😎👀 🏍️ 💨💨💨🚲💨💨💨💨🏎️💨💨💨💨💨 ⛓️⚙️🔩👨🏼‍🔧🦡⌛🛣️⚖️🧲🛠️🔧🧰🗜️⚒️🔨 📈🎥☣️🚳⚠️↗️↗️↗️🏆 🚀👀🦾🤘 👀 👀 🛵💨💨💨💨💨💨💨 👀 👀👨🏼‍🔧

Fuel surging is the word

Your welds look real good I use a torch so mine aren’t as nice looking

need to add one-way vent cap, incase of roll over

Boy, U R SO GOOD

Generally vents should be in the geometric center of the tank so neither right, left, fore nor aft movement produces a fuel spit situation. Baffling helps. But a center vent is best.

Just watched one of your older vids when the notification popped up

Maybe I'm hallucinating? but it seems like this project is taking longer than your past projects. don't get sick we need your content. I agree with you on the fuel tank calculation. I'm too lazy also.

Who else thinks that Chris and the other You Tube guys Grind Hard , Red Beard , Vasily etc. Should have some type of build off and meet up . To show case and be judged on their skills . Would be worth watching.

Looking good

Love it keep it up as always 💘

That’s a big tank

Man’s out here taking design tips from the Ford Pinto 😂 plz don’t get rear-ended and explode, this world needs ya man

Might want to put a guard on the chain between the chain and the tank. Chain breaking and punch a hole in the tank = bad day out in the woods.

I wish that I had a dollar for every time he gave the I'm not ready to leave for the collab speech lol😂

You should consider putting a bigger engine in. That engine may be powerful but it won’t have the right amount of torque to get it up any hills. And you’ll have to change the clutch every time you drive it

I just realized we were both working on gas tank videos this week so funny

Almost 11 gallons, greetings from south Germany 😅

Hell yeah been waiting on this 👍🏻

I know you've already got a plan for your next build, at least it appears that way as you're already designing and putting together parts for something. However, please, please consider doing a decent to large sized Quad Bike, all terrain, high powered, ride anywhere, anything but really really smart, stylish design. It's an area you don't explore enough considering the size of the builds, the freedom it could give you, whilst not taking months and getting out of hand. You could even go electric, all terrain, high powered, long battery etc and build something really special.

depending on the fuel pick up. half a tank

fuel tank 10.91 gallons roughly - volumn of internal fuel pump and wall thickness of the tank 10.5 gallons would sound close enough

In Stead of baffling you could’ve use fuel cell foam 👍

Looking allsome 👌😃👌🎉🌟🦇 from cruzerman

10.91 Gallons more you should see about extending the tank outside of the frame on all 3 sides to get a larger capacity then build a cage around the other parts of the tank to protect it! Or at least build a larger secondary tank and let it grav be able to gravitate feed into the trophy trucks tank from off the trailer! That seems like a much better solution for your off road vehicles with smaller tanks. Or you could get a plastic 35 gallon capacity fuel tank for like a 1992 Chevy truck and mount it to the trailer and you don't have to worry about venting or anything like that because they already are on the tank or on its matching fuel pump!

Those bricks should be on the payroll as often as they help 😂

Yes !

turning with that much stickout on a large part , keep the rpms down , if that sucker gets loose it can kill you

Thing is so badass. I want to build on3

tank looks cool, but you will need a bigger vent, and need to run it open both ways. then run it to the top of the cage then back back to the ground to help not losing gas in a roll over. they do make roll over valves that go inline ,ck them out.

10.9 gallons minus the pump slight space for baffling and the fact that it will not get completely filled due to the slight tilt so I'd say about 10 gallons.

10x14x18=2520cubic inches divided by 231=10.901 gallons. - thickness of metal and everything in there im so smart (i coppied that from someone actually smart)

awesome as always-did you start with an alum. roller for a boat trailer? looks like a big roller from a trailer haha Biltmore scrap yard? if so are there any more there in the alum pile? from a fellow off roader tank baffles are good.

41.3 liters, or 10.9 gallons. I would go with 10 gallons to compensate for the pump and devider inserts.

Hay FIY Semi trucks use a screw-in vent with a built in roll-over valve! Safety First

I want too buy you a I.D groover so you can part off without having to bust out the hand saw lol.

You can Google tank volume calculator and use the dimensions to figure it out when you need to know

About 10 gal bud, accounting for a 10% reduction for pump baffles etc

I think it might be time to get a fine extractor. No need to be getting sick from fumes…

you have a kapacity of 44.73 or to round it up 45 litres of fuel or 11.9 gallons

Here you go on Tank capacity 10x14x18= U.S. Gallons - 10.91, Imp Gallons - 9.08 or Liters - 41.30

Rally Raid Buggy... 😄
