Why A Clean Fuel Tank Is Important For A Fuel Pump’s Diet
Fuel pump replacement comebacks can be costly and can hurt your reputation. One of the leading causes of failure is the tank. If a vehicle gets 20 miles to the gallon, then more than 5,000 gallons of gas (from many stations) will go through the tank in 100,000 miles. During this time, sediment, rust and debris from the pump can find its way into the tank. Removing all contaminates is critical.
Explorer/Mountaineer Fuel Pump Tech Tip
Some 2004-’07 Explorer four door/Mountaineer vehicles may exhibit the malfunction indicator lamp (MIL) on with diagnostic trouble code (DTC) P0463 or an erratic fuel gauge concern. This could be from sulphur contamination in the fuel, causing an open or high resistance on the fuel sender card.
Diagnosing Inoperative Fuel Pumps
As I’ve discovered recently, times change and so do the procedures for diagnosing inoperative fuel pumps. Just a few weeks ago, I diagnosed a case in which the owner had started his vehicle for several months by spraying starting fluid (ether) into his truck’s air intake before he cranked the engine.

Tech Tip: Fuel Pump Installation Tips
After having identified the fuel pump as the cause of a failure, empty the fuel tank in an appropriate container or gas buggy. Before removing the fuel pump from the tank and to prevent contamination, clean dirt off the top of the tank.
Why Are Fuel Pumps So Often Misdiagnosed?
Fuel pumps have a high return rate because any number of things may prevent the engine from getting fuel. Common causes of no fuel include a plugged fuel filter, blocked fuel line, blown fuel pump fuse, bad fuel pump relay, electrical faults in the fuel pump wiring (opens, shorts or excessive resistance), a dead fuel pump or no fuel in the tank.
