If anybody can verify where it goes, if it's an OEM part or best yet, send me a parts diagram for this housing/regulator I would really be grateful.
My AutoEngenuity program says my pumps is running 99.9% and my fuel pressure at the housing tap is 50 PSIG. I "THINK" the O-ring is letting fuel bypass but need advie or a drawing to confirm.
Thanks in advance !!!!!

Mystery solved......................
The O-Ring was from the inside middle of my old filter.
Apparently the last time the dealer serviced it they crushed the filter in. It didn't line up in the notches and I found that the plunger (stem) was broken off and rattling around inside my old filter.
