Need input from the masses concerning fuel cell size

So in my search over the past couple of years I have noticed that all of the poly manufacturers of fuel cells do not make a cell larger than 16 gallon with a bottom sump. For general running around for an hour or two that's fine but for racing, long riding and being far removed from a fuel source this is a major headache. Yes you could buy a very expensive custom cell with a bladder and trap doors or use a bigger flat bottom cell and use fancy pickups but why not use something that is stupid simple. I've contacted a poly cell manufacturer concerning building a poly cell in the 22-32 gallon range but they want input to see if this is even a viable concept for them. As many conversations that I have had concerning this over the years I believe it is. Post up if you would buy one.

I probably would have bought one when I set mine up, if it came with the racing required sheet metal shell. I'd also say it should be a deeper than normal sump. with what we do, a deep sump would be very beneficial.

Just have them sell you a sell without any of the fittings installed. Jaz will sell direct like that (that's what I did). A I wanted to use a ATL fuel plate that I got form Ebay (Nascar take off).


If you want a bottom feed then just drill and mount the fitting. I have not see any rules in U4 that says you cannot do that. All the rules say it has to be in a metal container (steel or aluminum).

I've done that as well with Jaz. But I think your missing the post here. They will build a new product line with a bottom sump in a larger capacity cell for us if there is enough interest. Drilling a hole and installing a fitting in the bottom of the tank will not collect as nice as a bottom trough will. I know there is support for this, just getting people to post concerning it is the battle.

i noticed the same thing and wondered why they only went up to 16gallon with a bottom sump. i would have purchased a 32gallon with the bottom sump for my runner had it been an option at the time.
edit: with a deeper than normal sump for even better fuel pickup when off camber.

That's the idea. All of their cells have been designed around the roundy round guys. Their other sump'd cells are more geared towards the street rod guys. They are open to making one specifically for offroad. Design is wide open.

I'm running an aluminum 20 gallon sumped cell on my truggy, but if I ever get around to building a buggy or four linking my dads bronco in the rear I'd be down for a couple of poly cells. Especially if they have a deeper than normal sump maybe even with some built in baffling to keep fuel in it off camber if that's not too hard to mould into it.

That's the idea. What other options could you guys think of that you would want to incorporate? Design is wide open.

How about a poly cell in a metal can close or the same size as the RCI street rod cells? More tall then wide, I've got an aluminum 20 gal cell now that takes up way too much space because it's only 10" tall.

my deeper than normal sump idea seems to be top of the list.
must have a metal box option
baffling to prevent sloth, NOT FOAM. Even if it had a bunch of flat pillars sticking up offset. 4" wide and 3/4 the height of the cell. Or any kind of baffling to prevent slosh besides that shitty foam.

for the kind of wheeling I do, my 16 gallon cell is about perfect. I can go for a week on the Rubicon with no problems, and its small enough to fit where I need it.
I actually removed my first cell, which had a sump, in favor of one without. I would have kept the sump, but no one made a metal box for it. My first cell got hot in the sun, and warped really bad once, and always looked sketch. When I replaced it, I wanted one with a metal box to constrain it a little more and provide a little extra security.

That said - both cells were purchased as the tallest cell I could get - I need to save horizontal space for other things (like a big ass beer cooler ) and wanted the taller fuel 'collum' to keep the pickups covered. If I could, I'd get an even taller one that takes up less left/right forward/back space.

Baffles would be nice too.

Unfortunately, I dumped the picture off my phone a while ago. I was at Lane Automotive a few years ago and snapped a pic of a 32 gallon cell with bottom sump feed. I believe it was a Jaz cell, it had a bladder and white outer shell.

edit: found it.. it's bottom feed, not really bottom sump

Yeah I've seen those. Really need a wide bottom sump.
