Items you will need

  • Small fluid catch pan

  • 14-mm open-end wrench

  • New fuel filter

The Chevy 1500 model is also known as the Chevrolet Silverado 1500. The Chevrolet Silverado 1500 has an in-line fuel filter that catches and traps the sediments from the fuel before the fuel gets to the engine. Once the fuel filter traps the sediments inside of the filter, the fuel travels to the engine. Chevrolet recommends replacing the fuel filter on the Chevrolet Silverado 1500 every 30,000 to 40,000 miles.

Park the Chevrolet Silverado 1500 on level ground and set the emergency brake.

Remove the gas cap from the gas tank to relieve the pressure off of the fuel filter.

Slide under the driver's side of the Chevrolet Silverado 1500 and locate the fuel filter. The fuel filter is located inside of the driver's-side frame rail, between the driver's-side cab of the truck and the driver's-side rear tire.

Slide the small fluid catch pan underneath the fuel filter to catch the small amount of excess fuel inside of the fuel lines and the fuel filter.

Unscrew both fuel lines from the fuel filter with a 14-mm wrench. Hold the fuel filter with one hand, and turn the hex head on the fuel line with the 14-mm wrench counterclockwise to loosen and remove the fuel line. Do this to both fuel lines. Let the fuel lines hang down toward the catch pan.

Slide the fuel filter out of the round bracket from front to back. Slide the new fuel filter into the bracket from the rear of the bracket with the arrow on the fuel filter facing the front of the truck. The arrow that is stamped on the fuel filter represents the fuel flow through the fuel filter.

Screw both hex head fuel lines onto the new fuel filter and tighten them down with the 14-mm open-end wrench.

Put the gas cap back on the gas tank. To prime the fuel filter with fuel, turn the ignition on and off three times. Crank the engine on the fourth turn.

Inspect the fuel lines and the fuel filter for leaks. Turn the engine off.


The fuel-filter part number for the Chevrolet Silverado 1500 model truck is Hastings-3691-05041511.
