How to Replace a Fuel Pump in a Chevy Silverado

The fuel pump in a Chevy Silverado is electric so you should check the fuses and relays before inspecting the fuel pump itself. If you have fuel in your tank, but your vehicle has difficulty getting fuel, you may need to clean your fuel pump or replace it entirely. The Chevy Silverado comes in a variety of styles and trim levels and this may affect your choice of fuel pump.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Fuel pump kit
• Fuel tank sending unit wrench
• Torque wrench

1. Determine the fuel pump that your Chevy Silverado will require. This depends on the make and model and engine size of your vehicle. Models are equipped with a Vortec 4.3 L, 4.8 L, 5.3 L or 6.0 L engine depending on the exact model.

2. Disconnect the negative battery cable with a socket wrench. Relieve the fuel system pressure, drain and remove the fuel tank. Remove the retaining ring for the fuel sender assembly with a fuel tank sending unit wrench.

3. Note the position of the fuel strainer before pulling it off and discarding it. Unplug the electrical connection for the fuel pump and the fuel level sensor under the cover of the fuel sender.

4. Remove the retaining clip for the fuel level sensor and remove the fuel level sensor by squeezing the locking tangs. You may now remove the fuel pressure sensor.

5. Install the new fuel pump using the items included in the kit, especially the fuel strainer. Tighten the mounting bolts for the fuel tank straps 30 ft. lbs with a torque wrench.

6. Complete the installation by reversing the removal procedure.
