Help me find this part - WHipple related

My uncle has a 94 blazer k-5 that he put a 406 (or something to that effect) stroker in with a whipple supercharger. Sadly...it caught fire a few months back. The last piece of the puzzle to rebuilding it is this:

a fuel pressure relief valve for after the throttle body...any one know where to find one?

Whipple says they don't have them

fuel pressure REGULATOR...

should be able to adapt any aftermarket piece (that one even looks aftermarket) if you figure out if it is a 1:1 or a rising rate unit.

aeromotive makes great FPRs.
