Can i use my fuel pressure regulator from my 7m?

[86_sports_1jz]

i have an aeromotive FPR that i wanted to use on my 1j but i don't know if a 1j has a return line. Is it better to hookup the FPR on the return line or the line sending in fuel? Could i use the FPR for my 1jz?

Yes. It should work exactly the same.

I dont think you can use a FPR before the rail in the system or there would be nothing to maintain pressure in the system, it would all flow straight back to the tank.
