I want to replcae my stock fpr so i can fine tune the fuel pressure. what type do i need? will any standard perf fuel preesure regulator work? what parts do i need to hook it up? i have a fuel dampener bypass already on the car what size is it-6? and what size do i need from the fuel regulator to the fuel rail? i want to get this setup before i dyno tune Thanks Brett

The stock regulator bolts onto the rail with 2 bolts, just make a flange out of a piece of aluminum to replace the stock regulator, and drill/tap that flange to adapt to whatever line you are going to run to the regulator. Any EFI regulator with vacuum compensation will work. I like the Paxton/Aeromotive/SX units.

what size line do i need if just want to use the stock inlet of the fuel rail and what size is the fuel pressure dampener ends? thanks dave by the way i am going to with one then ones you listed thaey are alot cheaper and just as good if not better then the more expensive ones. its not justifid to spend 225 for something like the Aem fpr unit one lol i could just go afc for that price.

idont want to have to mess with drilling and tapping lines im just looking to bolt it up which i dont dont know what sizes i need ;( and ill prob mount the fpr near the intake manifold.

Well, the regulator needs to go on the discharge end of the rail, not the inlet.

I think the threads on the inlet side of the rail are 14mm, I don't remember the pitch. (1.5????)

k so what is the best way to hook this up dave?

If I use the factory 2JZ-GE Fuel Rail, what fitting can I use where the factory regulator is ?
A) The 1/4" NPT to 6AN fitting is perfect for the end of the fuel rail.


does this seem to be the right answer at the fuel dampener bypass kit has a-6 connectiion. or do i leave that untouched and run it from another fuel line> lol i am sort fo confuded that why i am asking all these quesitons thanks
