Heeelp. I just replaced both fuel pumps on my 1989 300TE with Meyle pumps and the front pump (where the filter and accumulator live) continually leaks. I have pulled it out 5 times now and used new copper washers but the freaking thing still leaks. What gives? It seems fine just after i do the job and take the car for a run, no leaks but when i go back to the car the next morning it has been leaking. It is driving me nuts. Any clues on what i can do here?
