Corvettes equipped with 4bbl Rochester Quadrajet carburetors have internal cartridge-type fuel filters that should be replaced periodically. Replacing the filter isn't difficult, but the fuel line must first be disconnected from the carburetor to access the filter. For the purposes of clarity, we're showing the filter replacement on a carburetor that has been totally removed from the engine for refurbishing; however, after removing the fuel line, the procedure for replaceming the filter is identical to what we’re showing with the carburetor mounted on the engine.
