Common Fuel System Issues

• Hard starting caused by a failing in-tank fuel pump
• Inaccurate fuel gauge readings from a worn sender unit
• Fuel delivery loss under load or at higher demand
• Intermittent stalling related to pump or sender wear
• Restoration work on classic Chevrolet and GMC trucks and SUVs

Installation Notes

Before installation, the fuel tank must be inspected and cleaned. The fuel tank lock ring and seal must be replaced; failure to do so will void the warranty. Confirm the tank is a 31-gallon unit with 4 outlets before ordering. This part cross-references Delphi (e.g., HP10009, HP10026) for the same application.

Spectra Premium fuel pump and sender assemblies are produced with engineering, manufacturing, and quality control processes intended to match or exceed the performance of the original equipment they replace. The SP12L1H is built for direct replacement service on select Chevrolet Blazer, GMC Jimmy, and related truck and Suburban applications.
