Servicing The Rochester Quadrajet Carburetor Photo Gallery
Install a new vacuum break hose-avoid kinks. Earlier Quadrajet models are prone to inlet thread failure. Damaged fuel inlet threads should be restored properly with a Heli-Coil thread insert. (Don't waste time with other methods.) A pleated paper filter fits behind the fuel inlet nut. Install gasket and nut. Tighten nut to 25 ft-lbs.
