this vehicle has to fuel tanks, one above spare tire, and one in the usual sub. Area. I changed the main fuel pump in top tank to remedy a pump whine and gauge inacuracy, but now has a whine from lower tank only when running for a period of time. Does the lower tank house a seperate fuel pump for fuel delivery or system pressure, and how much noise is normal?
