We talked about this in one of my oother threads. I found out my edelbrock fuel rail uses a LT1 style FPR.
Well I do a little searching online and I found that the LT1 was not the only gm engine to use the style of FPR. Craploads of vehicles use them!
I stumbled upon one on amazon and there is no real discription of it. At the bottom they show what other people have looked at. I found 6 delphi FPR's that look identical, but with just diffrent part numbers. Nothing in the discriptions about what their pressures are, or what the diffrence in them are. They all would bolt onto my fuel rail. But what pressures are they set at? I tried searching, but had no luck,
Part numbers I found where they all look identical:
FP10003
FP10004
FP10020
FP10026
FP10027
FP10300

Advance auto offeres a BWD brand adjustable one for like $56. I am thinking about just getting that one.
