Hi i have installed a bosch 040 in my r34 gtt it is now also wired on it's own seperate circuit everything works fine apart from the fact that after a few minutes of the car running the pump then develops this rather loud buzzing sound and left long enough the car won't get enough fuel to boost. the sound can be replicated by just started the car and letting it idle, it will happen after a while say a few minutes if i turn the car off and start it again straight away the sound will continue straight away, if i turn the car off for a couple of minutes it will take a few minutes again for the sound to develop when the sound is about to start i can hear like clicking/kind of slurping sounds almost coming from the pump, i'm thinking it is cavitation or turbulence with the bottom of the tank starving the pump maybe ? this has been a bit of a saga for me over the past months with other shit going wrong so i'm about ready to buy a walbro and sell the 040 because i'm fairly over it heh any help would br much appreciated thanks
