83 cj7 gas tank
Im starting my first ever endeavor into auto repair :D

I have an 83 cj7 thats been sittin a decade. My goal today was to get er runnin. Thank quickly turned into gas tank removal. Evidently, the tank wasnt drained and completely corroded. I already read the tank removal thread which helped me a ton with getting the thing pulled. Now Im in the hunt for a new tank. Seems like the various metal tanks are under 150 bucks, but the one plastic one i found online was over 400 bucks. Quick question:

Is plastic really preferred??? If so, I only found one online. An Omnix for 500 bucks!!! All the steel ones Ive found are under 150. So, Plastic of Steel? and If plastic is really the deal, anyone know where to get one at a bit more reasonable price??

My Jeep still has the original 40 year old steel tank in it. Its a California Jeep, so salt and corrosion isn't that big of a deal. You are in Sacramento, so again exterior corrosion shouldn't be a problem. As long as you use the Jeep interior corrosion should not be a problem either. If you want to go with a 21 gallon tank instead of the 15 gallon size, I believe you have to go with the poly tank, but I could be wrong. Anyway, welcome to JeepForum and the insanity known as CJ's.

Be sure to fill out your Jeep's profile so that when you have questions there is a quick reference for others.

By the way, I have spent a lot of time in the Sacramento area. Lived in Woodland for 18 years and worked in Sacramento a lot.

I replaced mine on my '84 CJ-7 with the same 20gal poly tank and it wasn't anywhere near that price, will look for the receipt and let you know who and where I got it from.. I know that one they shipped out was way too deep, but exchanged for the correct one no problem.. so, when you do order, give the exact/close measurements to be sure to get the right one first.. gas tank XL0051 from 4wd parts is the "wrong" tank.. way too deep, and that's where I got the correct one..

let the spending begin!
you have turned the first bolt which is the equivelent of pandoras box. i have the 20 poly stock, if you want to carry more fuel than you will upgrade to it. it will cost you $500. you will need the tank, sending unit, skid plate which encases the plastic tank and the vent valves. my opinion is to just replace the 15 gal tank with another metal one. welcome, this forum will answer all your questions. morris 4x4 has a good site to see most parts you will need.:cheers2:

Welcome to lost weekends wrenching.

The standard 15 gallon tank will outlive the rest of the Jeep. It is worth taking the whole assembly apart, cleaning it up and painting it. It only takes a few hours apart from paint drying.

so far, the toughest part of fuel tank replacement, is finding the hoses.. I never could find the correct inlet and breather hose for mine, had to take a couple and cut them, make the bends, then put them back together.. very restrictive..

I have a couple of 15 gal tanks. One is complet but hoses are junk. Sending unit is there. I'm not sure what year they are though.One has a much larger fill hose than other.Both are free of rust. P.M. me if interested.

The Jeep Forum CJ thread which helped me
That said ...
Here is a very good source for a plastic gas tank. Supposedly the closest to original.

Thanks for the replies boys. I found this site that seems to have the entire assembly, from skid plate to gauge. Anyone order from here?? Is this place any good?
Not sure about links on this forum, so here

CJ7 fuel assembly

If thats not ok, then use below and remove the space between the w w w
w w

they have a few options. a 21 gallon poly with sending unit and skid plate extension for 279 as well as just a stock oem 15 gallon. 6 extra gallons would be nice

VPALLARI 06-18-2013 06:50 PM

Im going with 15 gallon oem from the link above. I figure i may as well replace the sending unit as well. 2 more quick questions
1) Should I replace the lines up to the fuel pump and gauge while Im at it? since its been sitting so long, I dont want to get it back together and find out they need replacing.
2) I read about blasting and powder coating the skid plate since its down. I saw a post about using Rustoleum Spray On Bed Liner on it. Anyone every try this? sounds like a quick easier alternative to getting it coated at a shop.

firewalker909 06-18-2013 06:56 PM

I order most of my parts from Morris. They have good prices, quick shipping and great customer service.

I have used the Rustoleum in my fender wells. Holds up pretty well but it will chip. It is quicker and easier, but not as durable as powder coating.

Thanks firewalker. I wanted a good rec on morris, looks like a great site.
Ill give the bed liner a try since its easy enough to touch up if it chips.

BagusJeep 06-19-2013 04:30 AM

I personally woud not use bed liner, it is not an easy product to remove and it requires good preparation or it will lift and rust will creep in underneath. It is often a polyurethane based product which has its uses but protecting the underside is not one of them.

What system you will use on the underside is a matter of choice. I use phosphoric primer and a cheap enamel. Brush applied, cost $4 for the tank . But this is somewhere without deicing in winter. POR15 is apparently very good and a lot tougher.

The time now is 12:01 PM.
