This pdf file states

You can mount the 4307M regulator at any angle. For maximum
efficiency, mount it as close as possible to the carb or throttle body. DO
NOT mount the regulator on or near exhaust manifolds.

Also,
I believe if you have a trunk mounted fuel cell, you need to have a piece of sheet metal (a certain thickness)to cover the whole back area where the back rests in the back set.

I guess look up NHRA car saftey requirements to make sure.
If you are going to a NHRA track or just be safe in general.
