just wondering if any of u fellas can diagnose a problem thats been going on for a fair while now, gettin a hissin kind of sound coming from the rear of the car, im guessin its the fuel pump or something , i know for sure that there is dodgy s**t going on with the efi. hints??? i replaced the fuel pump last year

Hint - what about checking if its the fuel pump then. Is one side slightly lower than the other when you are on a level surface?

More info.
