How to Replace a Fuel Filter on a 1984 Chevrolet Caprice

Replacing the fuel filter on a 1984 Chevrolet Caprice not only can save you money at the gas pump, but in the repair shop as well. The filter removes sediment and debris from the gas before it makes it to the carburetor. While Chevrolet had no set recommendation for fuel filter replacement in the '80s, a good rule of thumb today is to replace the filter every 15,000 miles or less. Doing so will maximize your fuel mileage and improve fuel system performance. Anyone with a little auto-repair skill can change this filter in less than 30 minutes.

Tools Used: GM fuel filter wrench, Box wrench set

Replace a Fuel Filter

Open the hood and follow the fuel line to the side of the carburetor.

Slide the GM fuel filter wrench over the fuel line and onto the inner nut on the carburetor where the line meets the body of the carburetor.

Slide a box wrench over the outer nut and loosen the outer nut while holding the inner nut still. Use caution not to bend the fuel line.

Pull the fuel line away from the carburetor by hand. Pull the old fuel filter out of the filter cavity and dispose of it. Slide the new fuel filter into the filter cavity.

Tighten the fuel line back onto the carburetor with the two wrenches in reverse of how you removed it. Close the hood when done.

Tips & Warnings

Never work on a fuel system while smoking or around open flames.
