So i just replaced my OEM Bosch fuel pump. I also ordered the Riff Raff fuel pressure gauge kit and the 3 fpr spring kit and had ordered a fuel schrader valve fitting from ebay. I decided to hook up the gauge yesterday and was getting a reading of 84-92 psi with that little bit of back and forth. Doesnt seem right does it. Everything fuel related is original, just a new pump.
