Fuel systems for drag cars

We ran a Dakota in Stock Eliminator and Crate Motor classes. Our fuel cell was mounted in the bed of the truck. I wouldn't want a fuel cell mounted under the hood because if you front crash the car, chances are the cell will rupture. The fireball will be horrendous and think of where all of the fuel will be. As PBR said, #8 feed and #6 as return, and also as mentioned be careful of the chinesium crap that is out there. Only use quality fittings and line.
