Fuel cell suggestions
Anybody know of a fuel cell, or a standard size/form factor of a fuel cell, that fits neatly into the space of a C4 fuel tank? Thanks in advance.
I'm not going to be doing club racing, at least not any time soon, so rule sets shouldn't be a constraint.

I believe there was a division of fuel safe that would rotary mold a cross linked polyethylene fuel cell inside the factory tank, similar to what the factory tanks have. If I recall correctly they pioneered it for first responder fuel tanks so they were less likely to rupture when rear ended by some schmuck on the side of the highway (ie 70MPH and won't give room).
If you are looking at a ballistic bladder in a steel can, I had one made in the early 90s for a purpose built race car, before the polyethylene lined cells became more accepted.
As popular as the C4 still is, I would have to believe one of the cell manufacturers (Fuel Safe, ATL, Jaz, etc) would have a part number that fits correctly.
If you only want a polyethylene tank in a box, Tanks Inc has a "universal" fuel tank you could box up, it's fairly compact and comparatively inexpensive.

I'm still fond of the ballistic bladder, but that's what was "state of the art" when I started.

There was a OEM tank that was modified into a fuel cell years ago and marketed by Fuel Safe, I don't think it's available anymore, it had a custome bladder, foam and access plate.
This is a custom fab job where you make a rectangular cage to fit near the current fuel tank, either sized for an existing setup (there are several that fit dimension wise from Summit) or make your own to fit a Pyrotech or Fuel Safe bladder... if you want a bladder. If it's say 15 gallons, you could place it so the CG is lower and offset to the right. Also build it so that you can remove/service the fuel cell by removing the rear bumper cover, and that it's protected from exhaust heat.
