Moroso 63420 Manifold Filler Neck Kit
Fits most Chevrolet V8s

This piece locates the filler neck at the highest point of the intake manifold for those vehicles with a low mounted radiator. This way you can eliminate any air in the cooling system. It can be mounted with the hose outlet on either the left or right and it has a ½" NPT location for a temperature sending unit. It also has two ¼" NPT locations for water return lines used with aftermarket intake manifolds. It stands 3-1/4" high and it is cast from 356-T6 aluminum. Gaskets, bolts, washers, and a standard size filler neck are included.
