Where Does Delphi Quality Come From?
|
|
|
|
|
|---|---|---|---|
OE EngineeredOur parts are engineered with the same stringent standards applied to the parts we make for the top global OEMs. |
Durability TestedOur rigorous testing ensures reliability and readiness for the road ahead. In fact, our parts are tested up to 150,000 miles and in more than 20% ethanol. |
For Over 80 YearsOur expertise goes back to the beginning and we’re still innovating today. We’ve been a manufacturer of dependable fuel delivery parts for over 80 years. |
Innovative DesignWe utilize the latest OE technology and components to bring OE quality and durability to our fuel line and even make enhancements over some OE designs. In fact, we hold more than 30 OE-proprietary innovations and patents in fuel alone. |
Fueled by Innovation: Delphi's OE DNA
When it comes to choosing the parts for fuel delivery systems, reach for the brand that delivers the most advantages: Delphi. In the aftermarket, we’re best known for our fuel management program. As a world manufacturer in fuel pump technology and 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
- Contaminated fuel, which can cause rust or corrosion
- Excessively running a vehicle on an empty tank. Running near empty does not keep the fuel pump fully submerged and can cause the pump to overheat.
- 21% of returned fuel pumps failed because they operated in a contaminated system. Before installing a new pump, make sure to visually inspect for dirt, rust or discoloration.
Tech Tips
|
|
|
|
|---|---|---|
Start Your New Pump in a Clean EnvironmentReplacing 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 PumpHigh 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. Contamination in the system can cause restrictions to the fuel feed lines, fuel strainer, or fuel filter. 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 RepairThe 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, such as pilot lights or incandescent light bulbs. 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.

Not a Delphi brand pump
This pump is being sold as a Delphi brand. It arrived in a Delphi box, that had obviously been opened previously. The pump included is a cheaper pump that someone scraped through the brand name. Please see attached photo.
