Detailed Product Overview

Sparta PN4050 is built for select GM trucks and SUVs that use an in-tank fuel pump hanger assembly. It is distributed by Delphi, an OE fuel system supplier, and is aimed at earlier model, higher-mileage vehicles where restoring fuel delivery and sender accuracy matters. This assembly uses a 13.5-volt electric turbine pump with a 26.0 average flow rating, 12 to 29 psi operating range, and a 4.0 amp average current draw. The fuel sending unit is integrated, with resistance values of 1.0 ohm empty and 90.0 ohms full.

This part cross-references Dorman - OE Solutions 692-005 for the same application. PN4050 is a direct replacement choice for 1985-1991 Chevrolet S10 Blazer, 1985-1991 GMC S15 Jimmy, and 1991 Oldsmobile Bravada service needs. Use PN4050 when replacing a worn fuel pump hanger assembly on these GM platforms, including Chevrolet S10 Blazer and GMC S15 Jimmy fuel system repairs.

Common Repair Uses

• Hard starting caused by weak fuel pressure
• Fuel level gauge errors from a worn sending unit
• Intermittent fuel delivery from a failing in-tank pump
• Fuel leaks at the hanger seal or tank interface
• Noisy or inconsistent pump operation in older GM SUVs

The package includes the fuel pump hanger assembly with float arm, seal, lock ring, and instruction sheet; mounting hardware is not included. Replace the tank seal and inspect the fuel lines and electrical connector during service for a complete repair.
