Re: Adjustable fuel pressure regulator
Use a fuel rail w/o a return and use a aftermarket afpr w/bypass. similar to this: http://www.jegs.com/i/Aeromotive/027/13109/10002/-1

Re: Adjustable fuel pressure regulator
This may be a dumb question, but, how do I install one?
I have a fuel rail WITHOUT the return. Here is my setup.
Two lines running from the tank to the front.
One is the supply line
One is a return line
The regulator has 1 inlet and a return.
Where do I hook the regulator up?
Supply line to the inlet?
Return line to .....what?
What hooks to the fuel rail?
Does anyone have any pictures?

Re: Adjustable fuel pressure regulator
Did some more research to my own question.
Please look at these two diagrams and let me know which one is the correct way to hook up the regulator.

The top one is how I've always hooked up adjustable FPR's before.

The bottom looks like how you'd plumb a carb, and the top EFI.
