Detailed Description

Delphi HP10022 is an in-tank fuel pump hanger assembly engineered for rear-position applications on select Chevrolet C3500, Chevrolet K3500, GMC C3500, and GMC K3500 trucks with a 31-gallon tank. It is a direct-fit standard replacement for 1990-1995 models with code # VER, VPU, VRF, or VSF, and it excludes high temperature fuel sender applications. Delphi’s OE heritage shows in the integrated design, which supports fuel delivery and fuel level sensing in one assembly for cleaner service work and consistent operation. This part cross-references Dorman OE Solutions 692-001 for the same application.

What It Helps Fix

• Hard starting caused by weak or inconsistent fuel pressure
• Engine stalling from fuel delivery interruption
• Incorrect fuel gauge readings from a worn sender
• Fuel pump noise or reduced output from an aging in-tank unit
• Service issues tied to a damaged hanger, seal, or strainer

Installation Notes and Tips

Fits 1990-1995 Chevrolet C3500, rear; fits 1990-1995 Chevrolet K3500, rear; fits 1990-1995 GMC C3500, rear; fits 1990-1995 GMC K3500, rear. Confirm the 31-gallon tank and the listed code requirements before installation. Delphi notes that fuel tank contamination is a leading cause of premature pump failure, so cleaning the tank before installing HP10022 is recommended, and fuel tank cleaning kit FC01 is suggested. Verify connector style, outlet type, and sender resistance before service.

Quality Assurance

Delphi builds this fuel pump hanger assembly using OE experience developed through long-term supply relationships with major automakers. The HP10022 is a standard replacement part designed to match the original service application for the listed Chevrolet and GMC trucks.
