Detailed Product Overview

Delphi HP10261 is a fuel pump hanger assembly built for in-tank installation on select 1997-1999 Buick LeSabre, Oldsmobile 88, Oldsmobile LSS, and Pontiac Bonneville models. It combines the pump, hanger, float arm, and fuel level sender into one assembly to restore fuel delivery and tank level monitoring in vehicles using the specified module configuration. The unit is designed for gasoline fuel systems and uses a pin-style, 4-terminal female connection with an external strainer and three outlet ports.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

• Hard starting or no-start conditions caused by weak fuel pressure
• Engine hesitation, stalling, or fuel starvation under load
• Inaccurate fuel gauge readings from a worn sender assembly
• Fuel delivery issues related to a failing in-tank pump module
• Seal concerns after tank contamination or debris buildup

Installation Notes

Before installing HP10261, clean the fuel tank thoroughly to reduce the risk of premature pump failure and seal problems. This is especially important on 1997-1999 Oldsmobile 88 and Pontiac Bonneville applications with Fuel Pump Module Code HER, where tank contamination is noted as a common cause of repeat failure. Verify the vehicle’s module code, resistance range, and connector style before installation. Delphi recommends using a fuel tank cleaning kit when contamination is present.
