The Delphi HP10020 Fuel Pump Hanger Assembly is engineered to provide a reliable and efficient fuel delivery solution for 1985-1991 Chevy S-10 Blazer, GMC Jimmy, and 1991 Oldsmobile Bravada models. This assembly includes a fuel pump, sender, and necessary components, ensuring seamless integration and optimal performance. Designed to operate under extreme temperatures, the Delphi HP10020 Fuel Pump Hanger Assembly ensures quick engine starts and minimizes low-fuel hesitation, even with alcohol fuels and blends. The metal tubes in the hanger are routed to prevent contact with the tank or vehicle underbody, effectively eliminating noise and vibration during operation. The assembly's empty float height and float retention are meticulously matched to original equipment (OE) specifications, guaranteeing accurate fuel gauge readings. This precision contributes to consistent fuel monitoring and efficient vehicle operation. The innovative design of the Delphi HP10020 assembly results in lower failure rates, enhancing durability and extending the service life of the fuel system. Additionally, the assembly draws lower amperage, reducing the load on the vehicle's electrical system and promoting overall energy efficiency. The package includes the fuel pump hanger assembly with float arm, seal, lock ring, and instruction sheet, facilitating straightforward installation. To ensure optimal performance and prevent premature fuel pump failure, it is recommended to clean the fuel tank before installing the new assembly. This proactive maintenance step helps maintain the integrity of the fuel system and supports the longevity of the replacement part.
