Hi everyone and a Happy New Year! Has anyone replaced the failing 550 fuel pump gaskets with the Ricambi ones (#170511)? I took the fuel pumps out without any issues. It was pretty easy once I manufactured a tool to take off the pump covers. 65lb/ft was the breakaway torque, FYI. My original gaskets were partially dissolved so I bought the ones from ricambi but have trouble putting them on. I have them oriented correctly but there is a lip at the bottom of the hole of the gasket. throughly which the fuel pump is inserted. The question I have is whether that lip is the limit past which the fuel pump opening shouldn't go or should the fuel pump opening protrude about 1 cm past that lip? If it is the former situation where the fuel pump opening is not protruding, then the pump is sitting about 2 cm higher that the original factory set up when installed. If the fuel pump opening needs to protrude about 1 cm below the lip of the gasket, then it will sit ok but I'm afraid to tear that lip as it seems way to narrow to allow the pump to slide through. Any ideas? The picture attached is as far as the fuel pump will go without starting to really stretch that lip and possibly tearing it. Thank you for any feedback.
