Step-by-Step DIY Guide
Follow these steps carefully. Take photos at each stage for reference during reassembly.
Relieve fuel system pressure
Start your Chevrolet Silverado 1500 and pull the fuel pump relay/fuse while it runs. The engine will stall once fuel pressure drops — this prevents spraying fuel when you disconnect lines.
Gasoline is extremely flammable. Work in a well-ventilated area, have a fire extinguisher nearby, and do not smoke or create sparks.
Access the fuel pump
Most modern vehicles have the fuel pump inside the fuel tank, accessed via an access panel under the rear seat or in the trunk floor. Remove the panel cover.
Disconnect and remove the pump assembly
Disconnect the electrical connector and the fuel line quick-disconnect. Remove the retaining ring (a special spanner or brass punch and hammer may be needed). Carefully lift the pump assembly out of the tank, tipping it to drain fuel.
Install the new pump
Transfer the fuel level sender and any strainer/sock to the new pump if they are not included. Lower the assembly into the tank, align the locating tab, and reinstall the retaining ring. Reconnect the fuel line and electrical connector.
Test
Reinstall the fuel pump relay/fuse. Turn the key to ON (not start) and listen for the pump priming hum (2 seconds). Check for leaks at all connections. Start the engine and verify smooth idle and no fuel smell.
