i wanted to know which side the schrader valve is on, the in side of the fuel travel or the return line? i'm asking because i'm trying to figure out which side my fmu for the blower is on, i can't get the pressure to go below 34 with the regulator, and when i mat the gas it quickly jumps up to about 80 psi peaks at 90. i need to turn that down right much, and i have the regulator as low as it will go. i also do have a 255 lph fuel pump
