i just read the thread man and i dunno. i do salute you for thinking outside the box, but i think if you have got to have it in the car with you ida put it in the trunk, and facing 90 degrees the other way. so if it does fail then it will just blow to the sides of the car and out the hatch, then through your fuel tank, but thats another bridge that would need to be crossed. you do have the skill to turn it sideways. even if you do it in its location its in now. id scrap the box it sits in and just turn the damn thing sideways, then figure out your pipe routing after that. to be honest id still be worried about it hitting you if it blew up if it was in a box that was made from 1" steel.
