  • Delphi. In the aftermarket, we’re best known for our fuel management program.
  • As an OE manufacturer, we apply our high quality standards to every part we sell

Why Do Fuel Pumps Fail?

OE fuel modules and hanger/senders, which house the electric fuel pump, typically operate for 7-10 years before failure, depending on a variety of circumstances. Premature failures can be caused by:

  • Extreme hot/cold environments
  • Running near empty does not keep the fuel pump fully submerged and can cause the pump to overheat
  • Before installing a new pump, make sure to visually inspect for dirt, rust or discoloration

Start Your New Pump in a Clean Environment

Replacing the fuel pump strainer is required, but it is not enough if the tank is dirty. Make sure to inspect and clean the fuel tank as well.

Clogged filters are a leading cause of premature pump failure, so replace the fuel filter if it is not internal to the assembly. Internal filters are not serviced separately.

A Pressure Test is Not Enough to Condemn the Pump

High fuel pressure can often be attributed to a fuel pressure regulator issue or a restriction in the return line. The engine may run rich or fuel trims may be elevated.

Low fuel pressure can be caused by insufficient power or ground to the fuel pump or a malfunctioning fuel pressure regulator.

No pressure can be due to a faulty relay, fuse, wire harness, or oil pressure switch, tripped inertia switch, or dried test fluid.

What to Check Prior to Repair

The pump may not necessarily be the cause of fuel-related driveability problems or failures. So make sure to:

1. Confirm there is fuel in the fuel tank

2. Check fuel pressure

3. Check flow

4. Check fuel filter and pressure regulator

5. Perform a voltage drop test

6. Check electrical connections

7. Clean tank and inspect for debris

What Tools Will I Need?

Safety glasses and gloves are always recommended. Delphi also recommends a digital voltmeter, pressure gauge, and graduated cylinder. You should always have a fire extinguisher on hand.

Safety first

Never smoke or work near anything that could cause a spark or ignite fuel. Work in a well-ventilated area. Keep clean-up materials on hand, and clean up any spills immediately.

Always relieve fuel pressure prior to opening fuel systems. Store fuel in an approved container like a gas caddy or gas can.
