Willys Jeep Rear Gas Tank Conversion

[@motorv8N]

Great fabrication skills there. You’ve created a nice, neat and compact package for that fuel tank. Looks like factory!

[@SevenBarSalvage]

Thank you! I think my fab skills have improved a little over the original gas tank video haha

[@gillafunk]

Great idea. Excellent documentation and filming. Please do keep it up. 👏👏

[@SevenBarSalvage]

Thank you!

[@chiefsid]

Good Job! Nice fabrication work. Keep at it.

[@SevenBarSalvage]

Thank you!

I see this is 5 years ago, but, a horizontal square tubing ahead of the fuel tank, between the frame rails, would add some of the bracing lost when the V brace came out. The rear most cross member had that notch cut out of it too, so all the more reason to reinforce those frame rails. Better late than Never

[@SevenBarSalvage]

I made a follow up to this video a few months ago and reworked the whole thing! You’re right I made some errors in this video but I think second time is the charm 😉

[@pnw_outdoor_guy3980]

That’s a great idea. I will be starting on my dads 51 cj3a soon and wanted to get rid of the under seat tanks. I’m wondering if you could turn that tank around and run a filler hose up to the stock fill location on the drivers side. Then it would look more stock. Love your videos, you have given me great ideas.

[@SevenBarSalvage]

With a grinder and a welder anything is possible! I’ve got a new video coming out about this tank swap soon! Thank you for watching!

[@MrJeep75]

Adorable shop 🐈

[@michaelkaser2219]

Just curious and maybe this is a dumb question but what are the main reasons to get rid of the under seat tank? Is it no longer sitting on flammable liquid mainly and getting more capacity? I ask because I was toying with putting 2 under seats in so I can get more capacity, keep my rear storage by not adding fuel cell and keep under body clearance.

[@SevenBarSalvage]

The 2 main reasons was not sitting on the gas tank and seat placement I wanted to run later bucket seats. And you could run later seats and still run an under seat tank. Today I would say have both for extra fuel storage. It was a fun experiment! Good question!

Good idea

[@SevenBarSalvage]

Thank you!

[@stevenbillings1620]

Could you show the finished plumbing from the sending unit to the fuel pump including any return line and vents on drivers side. Any help would be great. THANKS.

[@SevenBarSalvage]

I’ve been gathering up the parts shouldn’t be too much longer there will be a whole video on fuel delivery! Thanks!

[@Alaska_Engineer]

The previous owner did the same conversion to mine and even with only having the F-Head, I’ve found that removing the rear K-Brace is a bad plan. I’ll be removing my rear tank and putting another K-Brace in the rear

[@SevenBarSalvage]

What issue did removing the brace cause?

[@Alaska_Engineer]

I’ve had this CJ for nearly 25 years and the conversion was done before I got the Jeep. I don’t wheel my CJ hard but now that I’m doing a frame-off I have now THREE disadvantages... 1) can’t tow a trailer to hunt or camp (I have a small military trailer) 2) no center pull point if you have to extract someone (or be extracted) 3) now that I’m doing a body-off, I can see that the frame crossmembers are beginning to work loose.

[@SevenBarSalvage]

Thank you I appreciate the information! Good luck with your project!

[@toodle171]

Thanks for showing this. I have a '57 CJ5 that I bought as a pile of parts and this is the one thing I am not looking forward to doing. Everything else you have done has shown me the way. BTW I'm thinking plastic tank, thoughts?

[@SevenBarSalvage]

I’m about to put a plastic tank in my cj5 (just a stock under seat replacement) I’m curious how good the quality is. I think plastic is better than metal most likely! Make sure to watch parts 2 and 3 of the rear tank conversion!

[@douglasedwards6636]

For the gas tank conversion is there anyplace where you listed all the parts required to do it. I'm assuming the tank is a stock from somewhere. Thanks in advance. I would be going the conversion in a 1960 CJ 5 and the rear of my frame looks identical to yours. I really don't want to use a fuel cell..

[@SevenBarSalvage]

It should all be in the description right under the video, if not I can email you the list. Make sure you watch parts 2 and 3 also I ended up reworking this for more clearance! Thank you for watching!

[@douglasedwards6636]

@@SevenBarSalvage I can't seem to find the list anywhere. If you could e-mail the list I would really appreciate it. There's no hurry. Hope you and your family have a Merry Christmas and a wonderful New Year. I, like so many, really enjoy your videos. Keep them coming.

[@marthawinne8843]

I am doing the same conversion to my CJ3B. How did you vent your tank? I am using the same tank and a '76 CJ5 rear fuel filler neck and hoses. Dave Winne Liverpool, NY

[@SevenBarSalvage]

Right now I’ve just got a vent screen with a check ball in it in case of roll overs. I’ve done some research on using the cj5 vapor canister and PCV system but it’s pretty complicated and expensive. Make sure you check out my latest video on the rear tank swap I had to fix some mistakes I made in this video! Thanks!

[@marthawinne8843]

www.tanksinc.com/index.cfm/page/ptype=product/product_id=98/category_id=-1/home_id=-1/mode=prod/prd98.htm This is the vent screen I plan on using. This link also has a link to an interesting article about tank venting. My tank appears to to multiple vent connections. Any idea which one I should use?

[@SevenBarSalvage]

I bought that same one I think it’s a good option. I don’t think wish port you use matters I’ll probably use the one on top. Thanks!

[@johnkreiner7842]

Ill have to do this after my engine swap.

[@SevenBarSalvage]

Make sure to check out the latest video I made some changes! Thank you for watching!

[@jamessparks7480]

what did you do for the fill tube?

[@MUN.A1988]

Why you do not sand the top frame and paint it. It will be endured more years to come? Although your modification for the position of the tank is perfect, but I wish to make all the car completelly restored and ready to be exported to outside with love rose🍭🍭🍭

[@SevenBarSalvage]

Check out my latest video on this it’s a lot cleaner than the first attempt! Thank you!

[@MUN.A1988]

I see your fingers are so close to the cutter..pls. watch out !!it is very danegerous.. Keep them a way back or make isolation between the cutter and the handle.SAFETY BE WITH YOU🍭💙

[@SevenBarSalvage]

Thank you!

[@MrJeep75]

You need something on the rear to fasten the corners of the body to

[@SevenBarSalvage]

I agree!

[@supertroopercj5]

I know this video is almost a year old but you put the skid plate on backwards. For anyone doing this conversion the skid plate flange that has the 4 mounting holes bolts to the bottom of the rear crossmember

[@SevenBarSalvage]

Its amazing how much you learn in a year! There’s not enough room on these old Jeeps to bolt it to the bottom of the crossmember. If I had to do it over again I would have made my own skid plate or even my own gas tank. Thank you for watching!

[@stevenbillings1620]

Have a 70 cj5 looking to do this fuel tank conversion. Info on where to find the tank kit would be greatly appreciated. THANKS.

[@SevenBarSalvage]

The tank, sending unit, and skid plate I bought for a 73 DJ5. The filler neck and fill tubes I’m going to use are for a 76 and later CJ5. Make sure you use a 15 gallon tank! Hope this helps!

[@hudsonkeelin2369]

Try going into Google and ask for gas tanks replaced tanks, don't asked for a jeep or willis jeep tanks to hard to come by You need measurements for your tank to fit.

[@hudsonkeelin2369]

The half inch piece you are cutting out why not plate it from top to bottom to build strength there.

[@SevenBarSalvage]

I think that’s a good idea! There’s some other spots on the frame I’m thinking about plating too. Thank you for the feedback!

[@hudsonkeelin2369]

@@SevenBarSalvage i love to work on classic automobiles.. I want to get a jeep myself. But right now the finance for buying one is not there for me. It takes money to build a great jeep, there are many great companies out there that make great parts for our vehicles I have a 2001 Chevrolet Silverado 2500 that I really want bring it up to better standards. It's only rear wheel drive and i would love to make it four wheel drive but it cost a bit, hopefully in time i can get my truck to where I want it Good luck with your jeep and hopefully you get it to your desire.

[@brianhof7599]

You need to wear gloves when you use a grinder with a cutoff wheel. And your grinder has no guard. Those fiber cutting wheels grenade all the time.

[@SevenBarSalvage]

My gloves disappeared I usually do. The guard gets in the way too much... I wear safety glasses and roll the dice on the rest haha! Thank you for watching!

[@DindoNuffin-e2x]

OH THE HUMANITY! This is why I purchased a 3rd Jeep. A 58 CJ5 MINT AND UNF##Ked with. To save it from young folks like this nice young man.

[@SevenBarSalvage]

I’ve said it multiple times on my channel, I would never part out or modify a restorable vehicle. This Jeep was way past restoring. Thank you for watching!

[@MD-xw3gd]

After watching longer ,I don't think you know how to use gloves right

[@SevenBarSalvage]

I appreciate your concern 👍

[@MD-xw3gd]

Hey. Put gloves on man.lots of tendons just under your skin that you use alot.
