Anyone know where to buy a fuel pressure relief valve? I've been searching the web and can't find one. I'd rather not shim the old one unless I have to.

Have you checked the relief valve for leakage? Kennedy has another recent post here that outlines how to perform the simple test for leakage.Originally Posted by jde0330

The LB7's do not typically leak or weaken. It's the LLY-LBZ-LMM that can be weakened IF they are beat up on by pressure cycling.
It's P0093 season and I am doing many 2001 LB7 ECM's with the same fix mentioned at the start of this thread.
Also seeing the same issue starting with LBZ and LMM P0087 codes.
