Fuel Cell HELP !!!

Freddie · 12-30-2007, 09:13 PM

I am trying to make sure I have enerything in order before I go to the first divisional race this year...

I have a 90 Mustang hatch, with a fuel cell mounted in the trunk, I had a box built around it but it didnt enclose it 100 %, the bottom of this is still the stock floor..

What do I need to enclose this in to become NHRA accepted?

I was thinking about mounting a small 3 gal. cell up front if this is legal?

Or should I just build a better box? how do I seal it?

Thanks in advance....

If it can be seen from the front , I think it has to be fully encased, no firewall between tank and driver is not legal uncovered.

You can mount a cell up front but it has to have tubes in front to protect against a front hit

check jegs or summitt if they offer something for your application

The 3 gal fuel cell is legal up front. (SP Pro S/st SG SC) For the purpose of safety the tech guys I deal with like to see a bar in the front of the cell.. But... If the car has a steel front end on it (ie fenders/grill) it is legal. I would check the rule book to make sure it has not been changed. I had it questioned at a National event from an out of division tech guy, he was going on about it having to be behind a tube in case of impact. I had a tech guy from my division come buy while the guy was proceeding to tear me a new one. I asked our divisional guy why I wasn't dinged on this at the last divisional. His reply was direct and to the point. Your car is built with in the rules, If you had a glass nose on the car you'd need a bar protecting the cell... The tech guy looked at me with a blank look on his face and asked me "the front end is fiberglass isn't it???? No all steel
