Delphi Fuel Pump Hanger Assembly P/N:HP10143
Delphi HP10256 fuel pump hanger for the 1989-1991 Chevrolet R3500 V8 5.7L or 7.4L and other vehicles supports the fuel pump and float arm inside the tank. This fuel pump hanger assembly is validated and tested for its application.
A fuel gauge that reads wrong, hard starting or a whine from the tank can mean the hanger or its float is worn. These signs alone do not prove the hanger is the problem; a clogged fuel filter is another common cause of hard starting.
The 1989-1991 Chevrolet V3500 V8 5.7L or 7.4L and the 1989 Chevrolet R2500 V8 5.7L or 7.4L are among the Chevrolet models this hanger fits. Each takes one. Open the "Vehicles it fits" section to check your exact model and engine.
