How to Change a Fuel Filter on a 1994 Chevy S10

Save

The fuel filter in your Chevrolet Blazer is responsible for keeping debris and sediment from entering into the engine. The fuel tank is equipped with a strainer that is attached to the fuel pump. When the pump suctions gasoline into the fuel line, the sediment at the bottom of the gas tank will also rise with the fuel. The strainer is responsible for keeping the debris from entering the pump. The debris that escapes the strainer will be picked up by the in-line fuel filter located toward the middle of the truck.

Things You'll Need

  • Crescent wrench
  • Socket set
  • Socket wrench
  • New fuel filter
  • Twist off the fuel-fill cap and place it to the side. This will help to take some of the pressure out of the fuel lines.

  • Locate the fuel filter under the driver-side door. The filter will be mounted to the frame rail.

  • Loosen the inlet and outlet lines with a crescent wrench. Pull the lines away from the filter.

  • Unbolt the filter-mounting bracket with a socket wrench. Take the filter out of the mounting bracket.

  • Place the new filter onto the mounting bracket. Ensure the arrow is pointing toward the front of the truck, as this designates the direction of fuel flow. Tighten the filter to the mounting bracket with a socket wrench.

  • Thread the inlet and outlet lines to the filter by hand. Tighten with a crescent wrench. Do not over-tighten the lines. This will strip the threading on the filter.

  • Screw the fuel cap back onto the fuel-fill nozzle. Turn the ignition key to the "Start" position three times. This will prime the fuel pump to send fuel to the injectors.

  • Start the truck and allow it to run for five to 10 minutes. Watch the fuel filter for any leaks to ensure the lines are tightened adequately.

Tips & Warnings

  • Place a small drain pan underneath the filter to catch any fuel that could still be in the fuel line.
  • Use caution when working around the fuel system. Gasoline is highly toxic and flammable.
