I was shimming the FPR spring this morning and had put it back to together and had 87 psi on the fuel pressure guage. so I removed the cover again and removed one washer! I started with Three, I relaced ever thing back together and now I have no fuel Pressure at all . I took it back apart and notice that the spring was gone. So I removed the cap and found the spring inside the pipe. Question!!! Inside the cap is there a retainer that keeps the spring in place.
