To ensure your Oldsmobile Bravada SUV is receiving the best fuel economy, you should change the fuel filter regularly. Changing this filter at 30,000-mile intervals will ensure the fuel system is filtering out any debris and sediment and keeping the Vortec motor running at optimum condition. The fuel filter is the last line of defense in keeping the fuel line free of debris. After constant use, it will clog up and cause the Oldsmobile to run roughly and idle erratically.

Removing the Fuel Filter

Step 1

Open the gas door and remove the gas cap. This will help to alleviate the pressure in the fuel line.

Step 2

Crawl under the Bravado and trace the fuel line from the fuel tank. The filter is an in-line filter and attached to the fuel line.

Step 3

Unsnap the fuel inlet line from the filter. The filter is equipped with a quick-connect fitting that can be unsnapped and pulled off the piping of the filter.

Step 4

Remove the outlet line off the piping of the filter. This line can removed the same as the inlet line.

Unbolt the mounting bracket holding the filter in place with a socket wrench. The bracket is held in place by one bolt.

Replacing the Fuel Filter

Step 1

Attach the new fuel filter to the mounting bracket and secure it to the frame. Tighten the bracket snugly with the socket wrench. Ensure the arrow on the filter is facing toward the front of the vehicle. The arrow indicates fuel flow direction.

Step 2

Snap the inlet line on the filter. Push the line on to the piping of the filter till it clicks in place.

Step 3

Connect the outlet line on the filter. This line will snap in place as well.

Step 4

Screw the gas cap back on to the fuel door. Close the gas door.

Crank up the SUV and let it idle. Ensure there is no hesitation or stalling.


  • Match up the correct filter according to the make, model and year of the vehicle by referencing the filter catalog at an auto parts store.


  • Use extreme caution when working with gasoline. Fuel is extremely toxic and flammable.
