Description
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. 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. 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. 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 Delphi Fuel Modules Delphi Hanger Pump Assemblies Delphi Electric Fuel Pumps And more As a leading OE supplier to the automotive industry, Delphi holds more than 30 OE-proprietary innovations and 150 patents in fuel module and pump design. As a result, our fuel pumps restore fast-pressure performance and system integrity to provide better pumping through less energy. Delphi fuel pumps feature internal springs for increased durability and enhanced stability, while a lower amperage draw places less load on a vehicle’s electrical system. Our fuel pumps include a large volume reservoir to better handle low-fuel situations and vehicle cornering, as well as fuel-level, gold-filled sensors for improved corrosion resistance. Other benefits of our fuel pumps include consistent pump flow, an enhanced filtration system for longer pump life and an OE-service body harness and connector for superior performance, durability and ease of installation. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
