Detailed Description

Delphi HP10020 is engineered for in-tank fuel delivery on gasoline-powered GM trucks and SUVs from the late 1980s and early 1990s. It is a direct-fit fuel pump hanger assembly for 1985-1987 Chevrolet S10 Blazer with 21 gallon tank, 1985-1987 GMC S15 Jimmy with 21 gallon tank, 1988-1991 Chevrolet S10 Blazer, 1988-1991 GMC S15 Jimmy, and 1991 Oldsmobile Bravada.

What It Helps Address

• Hard starting caused by weak or inconsistent fuel delivery
• Fuel gauge readings that are inaccurate or unstable
• Low fuel pressure conditions in the tank-mounted fuel system
• Fuel pump noise or intermittent pump operation
• Service issues tied to a worn hanger assembly, sender, or strainer
