The fuel filter on the Cadillac CTS is a silver cylinder about two inches in diameter and three inches long. Designed to catch any debris from the gas tank before it goes into the cars carburation system, the fuel filter can become clogged, causing the car to stall out or run rough. You can remove the fuel filter from the CTS in less than a half hour to determine if it needs replacing or just needs to be cleaned out.

Step 1

Locate the Cadillac CTS fuel filter underneath the passenger side of the vehicle, just in front of the rear tire.

Step 2

Open the vehicles gas cap to relieve the pressure in the fuel line and then reattach the cap.

Step 3

Lift the car up with a floor jack near the right rear tire and slide a jack stand under the axle near the tire.

Step 4

Lower the vehicle down so that it is resting on the jack stand and place a gas can underneath the fuel filter to catch any gas leaking from the lines.

Step 5

Slide the quick-connect fitting on the gas tank side of the fuel filter back and pull the fuel line away from the filter by hand, placing the end of the fuel line in the gas can to catch any leaking fuel.

Step 6

Detach the threaded fittings on the engine side of the fuel line from the fuel filter with an open-end wrench.

Step 7

Remove the fuel filter from the fuel line and place the end of the fuel line into the gas can to catch any excess fuel.

Step 8

Take the gas can out from under the CTS and remove the old fuel filter.
