I recently bought a summit fuel cell. i also bought a 11 gauge steel panel that i was going to bolt in place of the old tank and hand the cell from the plate. Unfortunately the tank hangs too low so i am considering putting the tank in the trunk. I also bought a 16 gauge steel sheet that i want to use to seal off the trunk from the interior of the car. its a fastback, so if i screw this in where the trap door used to be and use L brackets to screw it against the bottom, then will it pass tech? i also have the battery in the trunk.
