I read that. I knew the angle didn't matter but I just wanted to know if anyone had problems mounting the regulator in the back. I can deal with a little inefficiency if it saves me $100 as long as it still works.

I read that too but I'm going to weld up an angle iron and sheet metal cage for saftey to protect the cell. But I will install a piece of sheet metal between the trunk and interior if my track requires it.
I tried looking up the NHRA fuel cell rules but never found much useful info.
