Moroso Filler Neck Housing
Manifold-mounted filler neck base is identical to the one included in Moroso Kit No. 63420 without the filler neck or mounting hardware. Allows you to install a variety of bolt-on style filler necks (radiator cap or -AN style) or block-off plates, offering cooling system flexibility for both race and street applications. 356-T6 cast-aluminum base stands 2-5/16" tall, which locates filler neck at highest point to bleed off air on cars with low-mount radiators. Includes a 1/2" NPT machined port for installing a water temperature sending unit, and two 1/4" NPT machined ports to plumb return lines on popular aftermarket cylinder heads. The unit can be flipped 180° for either right or left water hose outlet location. Use with one of Moroso's Bolt-On Filler Necks Nos. 63460, 63461, 63465, 63466 or Block-Off Plate No. 63471.
