Ok, i got an adjustable fuel pressure regulator and fuel pressure guage. Now how do i check the pressure exactly? Which fuel rail should i hook it on and i think i remember someone saying something about unhooking a line...cant remember off the top of my head.

Thanks, Seth

 

i always heard about disconnecting the line, and hooking it up from there, but i would actually suggest contacting the manufacturer and seeing what they say about it, as i could also see different ones being hooked up using different methods, depending on how the whole system was to work.

 

Seth,

Connect the pressure gauge to the Schrader fitting on the right fuel rail.



Check the fuel pressure with the engine idling for the correct regulated pressure. Then disconnect the vacuum line from the spring cap of the FPR and read the gauge again. This is the maximum pressure the system will develop in WOT. Typical settings for maximum pressure are between 42-48 PSIG depending on your modifications.

 

Hey thanks a lot guys, got my AFPR today and adjusted it and car is running great. I love this board
