How to Replace the Fuel Filter on a Chevrolet Caprice Classicby Grace MclainUpdated November 07, 2017
Items you will need
Open end wrench set
Fluid catch pan
New fuel filter
The Chevrolet Caprice Classic has an in-line fuel filter that keeps any trash and sediments in the fuel from entering the engine. The gas travels into the fuel filter from the gas tank. When the gas reaches the fuel filter, the gas travels through the fibers inside of the fuel filter. The fibers trap any and all of the trash and sediments from the gas inside the fuel filter. The sediment-free gas then travels to the engine.
Park the Chevrolet Caprice Classic in a well-ventilated area. Make sure that the Caprice is also parked on a level surface.
Remove the gas cap from the tank. This will remove the pressure from the fuel filter.
Jack the rear of the Chevrolet Caprice Classic up and put the jack stands on both sides of the car. Position the jack stands under the frame rail directly in front of both rear tires. Lower the Caprice onto the jack stands.
Slide under the driver side of the Caprice between the driver-side door and the driver-side rear tire. Locate the round fuel filter that is attached to the driver-side frame rail. The round fuel filter is housed inside of a round bracket and has one fuel line coming out of each end of the filter. The fuel filter is held tight to the bracket by a small bolt and nut.
Slide the fluid catch pan below the fuel filter. Locate the white plastic clips at the end of the fuel lines. These white plastic clips secure the fuel lines to the fuel filter. Compress the plastic clips with your fingers until the fuel line unlocks from the fuel filter. Then, pull the fuel line off the fuel filter. Do this to both fuel lines.
Loosen the nut from the bracket bolt until the fuel filter is loose enough to slide out of the bracket. Slide the old fuel filter straight out of the round bracket. Put the old filter into the fluid catch pan.
Push the new fuel filter into the round bracket. Position the fuel filter so that the arrow that is stamped on the fuel filter is facing the engine. Tighten the nut until the clamp is tight over the fuel filter.
Push both of the fuel lines onto the fuel filter until you feel the plastic clips lock onto the fuel filter. Then, gently pull on the fuel lines to ensure that the fuel lines are secured to the fuel filter. Slide the catch pan out from under the Caprice.
Screw the gas cap back onto the neck of the fuel tank. Make sure that the gas cap is tight.
Prime the fuel filter with fuel by turning the key on and off three times. Then, crank the engine. Inspect the new fuel filter around the fuel lines for gas leaks while the engine is running. Turn the engine off.
Jack the rear of the Caprice back up and remove the jack stands. Lower the Caprice to the ground.
The flow arrow must be pointing towards the engine or the engine will not crank.
Never smoke around gas. Wear safety glasses around gas.
