The Pontiac G6 is one of the last vehicles made from the Pontiac line. Pontiac has always had a reputation of producing quality cars at minimal pricing. The maintenance was simple, and this applies to replacing the fuel filter. The Pontiac runs a fuel pump in the fuel tank, and is filtered out along the fuel lines. If the fuel filter gets clogged, then the car's performance will suffer.

Removing the Fuel Filter

Step 1

Unscrew the gas cap from the fuel tank nozzle. This will depressurize the fuel line.

Step 2

Disconnect the negative terminal from the battery. This will isolate the electric fuel pump.

Step 3

Locate the fuel filter. Trace the fuel line from the fuel tank to the front of the car. The filter will be located along the frame rail.

Step 4

Disconnect the fuel lines running into the filter by separating the tabs on the quick connect fitting. Once the tabs are separated you can pull the lines off the filter. There will be two fuel lines on the filter. Mark the top line as you pull it off with a piece of masking tape. The top fuel line can be marked "top." This will make installation easier.

Unbolt the mounting bracket with a socket wrench. The filter will come out once the bracket is loosened.

Installing the Fuel Filter

Step 1

Place the new filter in the mounting bracket. Tighten the mounting bracket with a socket wrench.

Step 2

Slide the "top" fuel line to the top position on the filter. Push the line till the quick connect fitting snaps into place.

Step 3

Connect the bottom line to the filter. Slide on till it clicks in place.

Step 4

Connect the negative terminal on the battery. Tighten the gas cap back on to the fuel tank nozzle. This will help to pressurize the fuel system.

Start the car to ensure the fuel is circulating smoothly through the fuel line. Listen for any hesitation or stalling.


  • Keep a small pan underneath the fuel filter when you are changing it out to prevent loss of fuel.


  • Use extreme caution when working around gasoline.
