Detailed Description

Sparta PN4020 is an in-tank fuel pump hanger assembly for gas applications, engineered for direct replacement on 1996-1997 Chevrolet C1500 Suburban, C2500 Suburban, K1500 Suburban, K2500 Suburban, and the corresponding 1996-1997 GMC C1500 Suburban, C2500 Suburban, K1500 Suburban, and K2500 Suburban. The assembly includes the fuel pump, float arm, sending unit, seal, lock ring, and strainer, helping restore both fuel delivery and fuel level reporting from a single service part.

This PN4020 assembly uses a turbine-style electric pump with a 13.5-volt rating, 6.0 average current draw, and a quick-connect outlet arrangement. The unit is built as a standard replacement with a metal body, external strainer, and specific-fit configuration for the listed GM Suburban applications. This part cross-references Dorman OE Solutions 692-128 for the same application.

What It Helps Fix

• Hard starting caused by weak or inconsistent fuel pressure
• Fuel starvation under load from a worn in-tank pump
• Inaccurate fuel gauge readings from a failing sending unit
• Fuel leaks at the tank opening when the seal or lock ring is worn
• Poor fuel delivery on high-mileage 1996-1997 Chevrolet Suburban and GMC Suburban models

Installation Notes

Install PN4020 only on the listed specific-fit applications and verify connector shape, terminal count, outlet style, and tank configuration before service. Replace the seal and lock ring during installation, and confirm the strainer is positioned correctly inside the tank. Because mounting hardware is not included, reuse or source any additional hardware required for the vehicle.

For best results, inspect the fuel tank for contamination before installing the new hanger assembly and confirm the electrical connector and fuel line quick-connects are fully seated after assembly.

Quality Assurance

Sparta is distributed by Delphi, an OE full-line fuel supplier, and is positioned for earlier model, higher-mileage vehicles that need OE-informed fit and performance. PN4020 is a standard replacement fuel pump hanger assembly built for the listed GM Suburban applications.
