Building a fuel tank

I can't seem to find a fuel tank that will fit my T the way I want with enough capacity so I thought I might try to build one myself. Looking for any good pointers or threads.

I've got the shape figured out pretty basic with not many welds to reduce the chance of leaks. It will be 33" long by 12" at the top and 8" at the bottom and 15" deep with a cut out to fit around my diff. I was thinking about sealing it with the tank sealer from Caswell as it has worked well on my choppers. Also I might as well add baffels.

I'm trying to figure out the fittings I need for a remote filler and fuel lines and was wondering if I had the right 45 degree neck. It looks like it has a supply, return and vent built right in. Then I'll just need a sending unit but I'm not sure if I should get the 0-180 or 0-90 ohm??????

Here's a picture of the neck and sending unit:

Also do you mount these before you weld it all up, I can't figure out how you'd get at the bolts on the inside??:whacked:

Anything else I would need or any sort of advice. I plan on using 16g steel and I have a tig welder but I'm not very good with it, is it okay to mig it?

Thanks for reading the long post,

The filler neck comes with a nut ring that goes on the inside of the tank, not too difficult to get the first couple screws started. The sending unit you choose depends on what the ohmic resistance of your gauge is.

Tig welding is probably the preferred way to weld the tank seams up, but a mig welder will work just fine if you're a good welder....

Thanks Dave, so I guess these parts would work. So is that blue tube the fuel line??

I guess this is a good way to practice Tig welding since I'll be able to have it on a bench and move it around:D .

I am in the process of building a new tank for the willys. I bought a fuel cell filler for $29 and a 90 ohm sending unit for $19 on ebay so I could keep the fuel cell I take out intact.

Running the formula shows 13.7 gallons capacity.

Should be enough, I had a 16 gallon fuel cell that seldom took more than 12 gallons and that was good for about a hundred miles of in-town running around.
Highway mileage got you about 140 - 150 miles between fill-ups.

Go here to see an article I wrote about fuel flange repair - which is, in effect building the whole darned thing except for the tank.

Hard to say which is which from that picture. Should be one for supply, one for return, and one for vent. Easy enough to figure out when you get it. With that type you'll also need to figure out a fuel pickup for the supply line,too. Nothing real difficult, same principal as an oil pump pickup in an oil pan....

Sorry Don, not actually sure what you mean. Is that a fuel pick up as in a submersible fuel pump or just a fuel line to the bottom of the tank. I think I need to get an electric fuel pump for my engine, would that be enough???

That was a good read C9 it gave me some ideas. I forget to use my lathe sometimes, I was gonna cut out a ring for my steering column until I saw you using the lathe for that same type of thing. I think the plasma cutter is making me lazy.
