The noise may start once the car has warmed up because the tank has had time to produce a vaccum in the tank which will then make the pump work harder!
yeah mate sounds possible.
Anyone know if the tank has a breather then? suppose as said above i could run the car with the cap off and see what happens.
gracie
isnt it more likely that it'd be worse when noisy? ie when we saw 9A?
