Chevrolet S10 / GMC Sonoma 2002–2003 Fuel Pump 19179493 25338726

Product overview

A new replacement fuel pump referenced to GM numbers 19179493 and 25338726. The listing shows it for the 2002 to 2003 Chevrolet S10 and GMC Sonoma compact pickups and describes it as corrosion-resistant. It is intended to restore dependable fuel pressure when the existing pump is weak or has stopped working.

Mounted inside the tank, the pump pushes fuel forward to the engine at the pressure the injection system needs. Worn pumps often announce themselves with a rising whine, surging at highway speed, stalling when the truck is hot or an engine that cranks but will not fire.

Vehicle compatibility

The part listing names:

• Chevrolet S10, 2002 to 2003

Technical specifications

Installation requirements

We recommend fitment by a qualified technician, as access usually requires lowering the fuel tank. Release fuel pressure, disconnect the battery and keep sparks and open flames away. Check fuel lines, wiring and the tank seal while the tank is lowered, and verify there are no leaks once reassembled.

Before dropping the tank, confirm the diagnosis by checking the fuse, relay and fuel pressure.

Fitment checks before ordering

These are left-hand drive North American trucks. Compare the GM number on your existing pump and confirm by VIN, engine and cab configuration before ordering. Contact us if you need help confirming the right part.

Keep the old pump until the new unit has been confirmed as a match.
