I looked but I need a quick answer....Anyone know what stock fuel pressure is? Im fixing to install an AMS fuel rail and Fuel lab fuel pressure reg. and wondering what fuel pressure to run on my 880cc injectors. Im tuned right now so I wanna set it to whatever is stock till I get tuned again on the 10th


Thanks

 

i think stock is between 40-44.

I have an aeromotive fpr set at 42 and it seems to work fine with stock injectors.

 

Set at 3.2 bars (too lazy to x14.7 psi)

 

(10)Measure fuel pressure while the engine is running at idle.
Standard value: Approximately 230 kPa (33 psi) at
curb idle
(11)Disconnect the vacuum hose from the fuel pressure
regulator and measure fuel pressure with the hose end
closed with your finger.
Standard value: 289 − 309 kPa (42 − 45 psi) at curb
idle
