My friend gave me an FPR (It is a rising rate 1:1 btw). SO what I'm wondering is where the best place to install this is?
I know the stock one on my '97 is near the rear wheels but I'd like to mount it somewhere along the firewall so I can actually read the PSI. I assume I can run fuel line from the stock location to the firewall, am I right? And one more thing, does this also mean the FMU/SFMU can be installed in the engine bay along with it?

Lol.. So you mean to tell me that your FPR that is a 1:1 will work with say a 12:1 FMU or 7:1 SFMU?? Either I'm highly misinformed or it won't work because the point of a FMU is to increase fuel per every psi of boost. With that being said, unless you have something to tune with (MS or portfueler, suggesting you don't since you have a FMU/SFMU) then you have no way to correctly compensate fuel. Because with a 1:1 + 12:1 FMU, you have no purpose with the FMU because the regulator will regulate it to 1:1 and then you won't have enough pressure for said fuel that you need.
Also you can't just "replace" your stock FPR. Not with a 1:1 at least.. Good luck, let me know how it goes. So I firmly stick by my "you can't use a FPR with a FMU/SFMU".

It can be done depending how you set it up.
First off your confusing a SFMU with a FMU. 2 different pieces of equipment.
1. SFMU is an FMU and Regulator combined with adjustable rising rate. There is no reason to run both but you can do it if you want to waste money and you dont know how to use the SFMU.
2. 1:1 with FMU is done the same way you would set up any other Regulator with an FMU. In our case the 1:1 with a FMU is pointless becuase the FMU makes having an aftermarket regulator pointless UNLESS your trying to lower your base pressure.

I know the difference between the two.. And as to your #2 - this is basically what I was saying, would be pointless hence it really won't work

And thats where your issue lies. Saying it wont work is not accurate. It will work just fine, its just too redundant to run the two regs together. I understand what your saying but your not getting your point across when you make a comment like "it wont work" because that alone is wrong.

From what Ive heard this is false too, providing you have MS to tune with. My car is a 95, meaning the FPR is on the fuel rail, so my plan for the turbo build is to install a Wally 255, and an aeromotive 1:1 FPR on the firewall to a 96+ fuel rail, and into some 600+cc injectors.
