I am trying to find one that will fit my needs.......-10 return , - 10 supply with sump , vent ( most I have seen are -8 and that is fine ) and 15 to 22 gallon capacity , since it is a thirsty street car most of the time.
Poly or aluminum , and preferably foam filled.
0-90 ohm sending unit.
These are what the perfect fuel cell will have , and I am warming up to the idea that I won't be able to get what I want without dropping more $$$ that I'd like to.
Have any of you added returns to your cells ?
I wouldn't be afraid to modify one if I had to and it wasn't a McGuyver kind of deal.
Thanks in advance.

Do you want a TRUE fuel cell or just a simple fuel tank with foam inside ?

I guess tank would be correct.........I don't need a bladder , but I wouldn't say no to one either , as long as it doesn't push the cost into aerospace territory.
Also modifying a cell with a bladder would probably be out of the question.

I would guess you dont weld.. a fuel tank is
pretty easy to build and you can make it fit
your needs.. this is one I built for my
Rampage.. its 18 gal with a sump.. I use a
external pump since I changed over to EFI
after I built the tank.. it has a sending
unit and a few lines on it

I've always switched to a -12 outlet fitting, and then used the old one, and installed it to the top of the cell for a return.

Look at the universal 60's Mustang tank.

I don't weld aluminum , and have the pics to prove it.
Did you bother with foam in that one , Mike ?
I like the changing fittings approach , and will definitely keep that in mind.
That is the most likely way this is going to play out.

I have a stock tank with the C/E sump welded on it and a return fitting plumbed into the rt. front corner , but with the Ford rear and the brace , it is going to be too tight in the stock location.
I figured to upgrade to a " cell " style tank , move the weight back some and sacrifice a little trunk floor.

No I didnt use foam.. I put 2 baffles in it for slosh

There are people who build custom tanks. A simple rectangular tank with the fittings, cap, mounts, etc., should not be too bad. But it will likely be more money than a mass produced piece.

I could probably get some aluminum cut up and have it welded.....baffles would be good and I could put the fittings where I want them.
I'll price materials and a sending unit.
How thick would you recommend ?
.090 or so should be O.K. I think.
Did you set yours in the diamond plate box , or is it made of .125 diamond ?

.062 is fine

I disagree, especially for a street car, unless its maybe 6061, you can stick a screwdriver thru it, and you are not using a bladder, right? 15-22 gals exits a tear/puncture pretty quick, by the time the driver smells it, best if you are wearing a 3.5 fire suit. The weight difference is minimal going to .125" in the big picture, and your welder will be happier.

15-22 gal. is a lot of weight. Not your typical race car tank. I would be afraid of .062. Stainless might be a better option. I've gotten decent quotes from Boyds in Florida. Maybe see what they have to say.

If your scared of .062 put a skid plate under
it with a gap... I had 30+ years of building
tanks.. 6061 is hard to bend with out a nice
radius.. stainless.. is pricey
