Mercury 1W7Z-9424-AAA Manifold Hardware Kit

To remove the intake manifold, you need to drain the cooling system and disconnect various hoses and cables. To identify and disconnect electrical and vacuum connectors. This requires removing the distributor to relieve fuel system pressure while disconnecting the fuel supply and return lines. For carbureted applications, this step will also require removal of the carburetor. It may be necessary to loosen clamps on these hoses and remove them from their connection points. The air intake plenum must be removed by unbolting coolant pipes if it is present. You should then proceed by loosening the lower intake manifold bolts and nuts as well as removing them completely. In this way, one can lift up the manifold checking that all bolts have been undone too. Use guide pins for installation together with sealant and gasket adhesive. Gaskets as well as end seals are required after cleaning mating surfaces.
