My gas tank is leaking around the sender. I thought it might be the rubber seal, but when I took it out, it looked good. I cleaned the mating surface, put everything back, and replaced the hose while I was at it, and it started leaking worse. I took it apart again and tried putting some RTV around the seal, but that didn't help either. None of the car parts stores carry the seal without having to get a new sender, and the Ford dealerships' computers don't go as far back as 77. I'm going to give Phil a call and see if he has some, but if not, do you have any ideas? Am I just going to have to get another sender?
