How to Change a Gas Filter on a Buick Regal

26

Although the Buick Regal has gone through several generations of design changes in its history, the function of the gas filter remains the same: to strain out pollutants from the gasoline before it reaches the engine. The gas filter is attached to the frame rail of the chassis below the car. Even though the exact location and installation procedure varies with the year and model Regal you own, the process for removing and replacing the gas filter is similar throughout.

Tools Used: Tools, Disposable towel, Car jack, Tire iron, Jack stand, Wheel blocks, 2 crescent wrenches

Change a Gas Filter

Open the hood of your Regal. Locate the small black cap on the fuel rail in front of the gas injectors. Pull off this cap to reveal the gas pressure valve. Cover this valve with your disposable towel. Press the valve down to lower the pressure of the gas lines. This safety precaution prevents gasoline from spilling in your face when you remove the gas filter.
