The Hella fuel pump and sender assembly combines fuel delivery and fuel level monitoring in one electric unit.

  • Hella part number 358302721 for catalog matching

Product Details

Hella 358302721 is a fuel pump and sender assembly that serves two functions in one unit: it moves fuel from the tank to the engine and reports fuel level to the instrument cluster. This integrated layout reduces the need to service separate components and supports consistent operation in vehicles that use an electric in-tank fuel system. It is a direct-fit style solution for 1991 Chevrolet S10, 1989 Chevrolet S10, 1991 GMC Sonoma, 1987-1989 GMC S15, and 1985-1988 Chevrolet S10 applications listed with a 13 gallon fuel tank. This part cross-references AFE3637S for the same application.

What It Helps Solve

  • Hard starting caused by weak or inconsistent fuel delivery
  • Fuel gauge readings that no longer match tank level
  • Intermittent engine performance from a failing in-tank pump
  • Service issues when the pump and sender need replacement together
  • Fuel system repair needs on Chevrolet S10, GMC Sonoma, and GMC S15 models
