Hi, Can anyone tell me if a Focus petrol pump should be heard quietly humming inside the car, would like to know if its normal or not. Bought 06 Focus Sport 1.6 petrol 2 weeks ago ,only 42000 on the clock, already been back for misfiring, turned out to be wiring connection. I've got 3 months to find any other problems while under warranty. Thanks for any replies.

in short yes you can hear them
