As far as the FP being new I went through 3 in my GN (Walbro 255) in the box NEW that had problems. G/L gremlin suck !!
Yeah took me a bit to find the schrader valve normally they are in the front, on this rail it's right next to the fpr. When I got the car the FPR vacuum line was plugged off, i hooked it up as the factory intended and the pressure is dead on.

I may try another module here, it's a lifetime warranty one. Gonna try a coolant temp sensor first as the one that I pulled out today looks like the original lol
