You might also want to read up on how to check the 4 different system fuel pressures. Should be 4 it goes like this: rest pressure after system is shut off and wait about 5 minutes it should hold pressure see specs.
cold start pressure at startup running pressure after warmup and deadhead pressure ( max pressure) that the pump is capable of. read the precautions especially on dead head pressure as you dont want to hurt the pump.
I found a digram for the system and number 12 looks like the photo.It is the auxiliary air valve ( cold start up air regulator) anyhow this pdf ( download it so you have it) is at:
Looks like good info.
