building a gas tank?!
Go figure the Heep has a leak in the fuel tank, Instead of going original I am looking at a 30gal barrel, welding the lid on it and welding a fill tube to it. With the scrambler, I have the room in the bed, also it elevates the tank from under the frame and any low hazards...Also it would be almost free! I know that I will need to add a vent to it, But am I missing aything else? I also know that I wnt have a sending unit for the gauge. factroy tank will run me near $120 + any misc fuel lines/tubes. not to mention that it is still under the jeep. The barrel I am looking at are the ones gear oil come in for semi trucks. they look like small skinny 5gal drums.

Weld in a baffel to keep the fuel from sloshing around during cornering, off camber and hilly driving. Otherwise the fuel may not be siphoned from the tank.

Some barrels are made from pretty thin steel. The big 55 gallon drums are thicker, but too big. You mentioned welding the lid on. That would be a trick with the thin steel. Another problem is that barrels are not an ideal shape for the application - because of the round shape they take a lot of room for the volume. If I were going to put in a custom tank I'd weld up a box to fit the available space, and use 12-gauge steel.

I didnt think about the baffle, Ill have to look into it. As for the drum, it is the same size as a bolt in tool box, so it shouldnt take too much space. Ill get the drum tomorrow and check thickness. As for welding the lid, they come "clamped" on with a rubber gasket for a seal. Im just not sure of the rubbers compatability with gas, or if there was an impact the lid popping off, thus I was looking at welding. I also thought of 2-5gal jerry cans as a tank.
Remember this is a Cheap Heep.

just spoke with a buddy, says his friends have done the same as what Im looking at, and the metal flakes apart from the drum...So off to boat tanks now.

First off, you don't 'NEED' baffles in a jeep fuel tank.
I've been inside three tanks this week, and none of them had a hint of a baffle.

If you 'Want' a baffle, it's nothing more than a divider looking piece welded in with slots or holes near the bottom of the tank to let fuel pass, but not 'Slosh'...

Baffles are easy, get some of the fuel safe foam that is used in fuel cells.
Very porous, easily lets the fuel in and out, but keeps it from "Sloshing'.

The make everything from large blocks you fit in before welding the cell shut, to balls about the size of ping-pong balls you put in after the cell is completed,
And most of the places that sell fuel cells will sell you the baffle material.

I think I got the last chunk I needed from Summit Racing if I remember correctly...

If you plan on running a fuel gauge, make sure you make provision for that gauge arm to swing and not bind up with your baffle material.

Depending on what fuel sender you are using, that can be a REAL pain in the butt!

While I applaud anybody trying to "do it themselves", I hope I'm in your WILL on this one. A gas tank isn't something I'm willing to play with........

I think a boat tank, or a similar fuel cell is the way I'd go........

Gotta be safe.........

Sounds like your gonna have a lot of fun with this Heep!

a guy from the local club has a 20gal poly tank for a cj he is gonna give me for less than $100. Ill look at it tomorrow to make sure it will fit. Then while the tank is out Ill see about replacing the rear half of the frame.
Thanks for the help. As always the pics are on my sight

You'll need a steel skidplate to go with that tank.
