Delphi HP10026 is engineered as an OE-style fuel pump hanger assembly for older GM fuel systems that require a tank-mounted unit with a float arm and integrated sender. Delphi draws on long OE experience supplying major automakers, and that background is reflected in the fit, function, and component layout of this replacement assembly. This part cross-references Dorman OE Solutions 692-033 for the same application. It is a strong match for Chevrolet Blazer and GMC Jimmy fuel system service, as well as Chevrolet and GMC Suburban models listed below.

Common Fuel System Problems

• Hard starting or no-start conditions caused by a weak in-tank fuel pump
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel delivery loss from a restricted or contaminated strainer
• Poor engine performance from low fuel pressure in GM truck and SUV applications
• Fuel tank service issues on Chevrolet Blazer, GMC Jimmy, and Suburban models with 31-gallon tanks

Installation Notes and Tips

Confirm the vehicle has the correct 31-gallon tank and harness code before installation. Clean the fuel tank thoroughly before replacing the pump assembly, since tank contamination is a leading cause of premature pump failure; Delphi recommends using fuel tank cleaning kit FC01 for this service. Verify electrical connector style, outlet type, and sender resistance range against the original unit before reassembly.

Quality Assurance

Delphi builds this fuel pump hanger assembly using OE heritage and application knowledge developed through decades of supplying major automakers. The HP10026 is a standard replacement part for select Chevrolet and GMC fuel systems and is backed by Delphi’s OE-focused engineering approach.
