Any stock-replacement FPR's available?
Does anyone know of a company that makes an FPR that will just replace the stock one (and hopefully flow more and/or operate at a higher pressure differential)? i seem to be massively outflowing the stocker, I see 60 psi fuel line pressure on occasion (only running 6 psi of boost). Anything that'll just bolt up, or do i need a whole separate unit and the associated lines etc?
Thanks!
Thanks!

The only time the pump would be able to outflow the stock FPR would be at idle. If you only see high pressures during boost, and low pressures at idle, it would be an indication you FPR is working correctly. IIRC the stock FPR is a 1:1 reference, so at the base pressure of 34-40 psi, 60 psi at only 6psi of boost is excessive.
To test the FPR, refer to the factory service manual: http://www.rotaryheads.com/PDF/2nd_g...tems_turbo.pdf
The info you need should start around page 68.

Yea, I've read the FSM on it and know how its supposed to working. However, at idle, at 6 psi, pretty much any time the car is running the fuel pressure is 55-60 psi, and it doesnt change with intake pressure or anything else. When I shut the car off, it drops down to 40-43 psi and holds there (sloooowwwly bleeds down), so I think the FPR is trying to work, but the pump is just massively outflowing it.
Anyway... What aftermarket (adjustable or fixed) FPR's are out there that people have used with the 7?

You never state the obvious thing you should have stated. Which is, what fuel pump do you have right now in the car? Stock or wallydo or???
