Thumping noise from rear of car after stopping engine
I have a 95 EF II Falcon Sedan. Lately I have been hearing a thumping noise coming from the rear of the car when I turn the motor off after driving for a 40 or so kilometers on the freeway at 110kmh. The noise happens in 1 second intervals then slowly these intervals get longer then it stops. I think it may be coming from the fuel tank. I have been having trouble with a whiny fuel pump lately and I intend to replace it shortly. Does anyone have any ideas? Are these two symptons related?
