How To Replace A Chevy Blazer Fuel Filter

The Chevy Blazer is an all around good small utility vehicle, and if you find you are not getting the best performance from your Blazer, you could have a clogged fuel filter. The fuel filter is designed to capture impurities from the fuel or any other contaminant that may have gotten into the fuel system. When you do regular maintenance, you should change all the filters.

Here are the instructions on changing the fuel filter on your Blazer.


  • Screwdriver
  • Clean catch can
  • New fuel filter
  • Instructions

The fuel filter is located on the driver’s side inside the frame of the truck. It is a silver cylinder that has a fuel line attached to both ends of the filter.

  1. Use a new or clean catch container to capture any fuel that may drain out once you disconnect the filter. You will be putting the fuel back into the Blazer, so take care not to contaminate it or use a dirty container. Take note of the position of the filter in order to put the new one in the right direction.
  2. Use a screwdriver and unscrew the straps that hold the filter in place. Put the filter away from the straps.
  3. Remove the fuel line on one end of the filter and allow it to drain. Once it has drained, remove the filter from your Blazer.
  4. Replace the old filter with your new one by screwing it back into place. Make sure that it is in the same direction.
  5. Secure the straps in place and make sure all your connections are tight.
  6. Start your engine and make sure you do not have any leaks in your lines. Once you have checked everything, turn the engine off.
  7. Place the drained fuel back into your tank. If you used an old or dirty container to capture the fuel, dispose of that fuel in a responsible manner rather than replacing it into your vehicle.
