I replaced the gasket that seals the fuel pump access cover in the top of the fuel tank. I noticed gas fumes inside the car and after filling the tank one day I parked it nose down hill in my parking lot. Gas was running out in front of the left rear wheel well. Moved the car around and removed the inspection cover under the rear seat (fuel pump access ) and saw that fuel was leaking around the gasket. Replaced it with a new Mazda unit, but it still leaks! The mating surfaces are fine, no rust or defects. Just wondering if anyone else ever had this issue. I did notice that the original gasket had what appeared to be some type of a "film" like maybe a thin coat of a factory sealer on it. I have some fuel resistant permatex, but I know there aren't many affordable fuel resistant sealants available. Porsche used to have a very expensive sealer that they used for these type of issues ( we used some once to repair a minor fuel cell issue to get us through the race season until we could send it back to the manufacture for a real repair) but is there anything else out there? I have MotoSeal 1 Ultimate Gasket maker Grey that I may try, just wonder if anyone else ever had this issue? Gasket cost $22.00 from Mazda, so I don't want to try my luck with another one...yet! Tank is full now, so I need to burn off some fuel before I try the sealer...once I get the clutch slave bled properly. Nothing like a 21 year old car and no garage!
