Anybody have recommendations on bladder fuel cells?
and
Has anybody sacrificed an OEM gas tank to mount the fuel cell lower in the trunk, but maintain the original looks? I literally just thought about doing that one...never seen it done before, but I'm sure I'm not the first. I know it wouldn't be a lot lower, but anything is better for center of gravity.

Post this question over at pro-touring.com Quite a few of those guys are running bladder systems and some are building "unofficial" tanks(too much liabuility)

Safety rules don't allow 'diy', unofficial tanks, at least for the events I'm researching. I'm describing using the sheet metal of an original tank with the top cut out and mated to the bottom of the trunk pan, allowing the 'cosmetic camoflage' of the fuel cel hanging out the bottom of the trunk the 10" or so I think it would allow.
The OE tank shell would only be for the original look from the rear.

Thanks for the tip...I'll check that site out.

You are looking to run pony express or silver state challenge, no? They will certify the tank if after it is built yo send it out to fuel safe and have them install the bladder-like I said, check out pt.com. We discuss this in detail over there. ALOT of the guys are building cars for this event-including myself.
