My sense of smell is supper sensitive, (reminds me need some deodorant), but also my hearing.
Only just noticed how much noise the fuel pump makes, like a quite whine in the background.
Or is it on it's way out?
Have you got one or two fuel pumps in yours? Does the noise go away depending on how much fuel is in the tank? I think I have a noisy fuel pump, sounds like someone trying to send a Morse code message... hope its not SOS
