Heads up on Delphi pump seal
I just replaced my fuel pump with a new Delphi I bought on line. On filling up with fuel I noticed a leak under the car so back into the install and tighten the pump retaining ring some more. It surprised me in that I was able to give it over an extra 1/4 turn- my bad I figured. Next day I notice another leak. Inside again but this time I pull the pump to see if I'd buggered up the sealing ring. The ring has fallen into the tank but upon examination, it's soft and swollen. Fortunately I have another seal from the fuel filter change out so I'm able to repair it. Looking closer at the old/new seal I see it says 'diesel fuel only' on the seal. Somehow the seals must have been mixed at Delphi? New one on me. Could have been a real problem if a fire was the result though. Might be a wise idea to look at the replacement seals from now on.

I remember a lot of concerns in the past about replacement seals being marked diesel fuel only, even ones from MINI dealers. This was posted by one of the vendors. https://www.northamericanmotoring.co...ml#post4208252
Maybe ECS, Way, or another vendor has more info to clear up the confusion on the seals being possibly mis-marked, or what the correct part number is for gas seals.

+1 Yep, its the same seal. What you have to do is seat the new seal and then twist the ring down, some people light grease the seal if its tight.
