Sorry I'm not to sure if this is in the right section I didn't know where it would need to go lol. So anyway i noticed this sound yesterday coming from which sounds like the inside of the car. Its everytime the car is in a high gear at low revs, when you put your foot down it sounds abit like a fan belt screeching quietly but then stops after the car has hit boost. The only thing I can think of is that it may be the fuel pump as I have stripped out interior I can hear it right behind my seat, I got the other half to drive it while I clambered into the back it sounds like it's coming from that area but it's not very loud, sounds like its underneath sort of thing. I did have a walbro pump fail on me couple months ago after having it installed for literally 11 months, now I've got another walbro, just wondering if it's failing again?
