Moroso Filler Neck Housing

These Moroso manifold-mounted filler neck housings are designed to allow you to install a variety of bolt-on style filler necks or block off plates offering cooling system flexibility for both race and street applications. They locate the filler neck at the highest point to bleed off air on cars with low-mount radiators and can be flipped 180 degrees for either a right or left water hose outlet location.
