There is no fuel pressure sensor on SR20DET's.

so how do i hook up the fuel pressure gauge? where do i hook up the sensor that came with it? thanks

Is it a vacuum gauge? If so id say put it on the FPR, but I havent looked into where to put it yet.

I know the GReddy Fuel Pressure gauge comes with an inline sensor. So you probably need to unhook the fuel line from the filter to the rail and put the sensor in between the two.
