Hi again. I got a more advanced scanner and poof that issue is gone but I have another.
Let me know if you want this in a new thread:
On Memorial day, I replaced the (return-less) fuel pump. I hacked it by going thru the floor pan, but saved untold frustration and time so am OK with the back-yard mechanic hit to my ego :). Since I got the pump on a holiday and dealerships weren't open, I had to re-use the old pump-to-tank seal. It was a bit stretched out and didn't sit in the groove that well, so I wasn't surprised to see gas on the ground when I filled it up later in the week after pulling a P0442 code. I ordered a new Motor-craft seal and put it in today.
I was dismayed to find that it still leaked. I removed the locking ring and made sure that the grove and seal were clean then re-installed it, only to have it leak again. Third time I re-cleaned and inspected to make sure there was no debris and that the pump cover laid flat before I secured the locking ring again. It continues to leak around the seal.
I've replaced several sending-unit/pumps before and haven't had this issue. I have always re-used the locking ring but am wondering if not getting a new locking ring for this vehicle might be the issue. Your thoughts?
