Description

Moroso offers manifold filler necks in a variety of styles, materials, and finishes—for applications from 1955 and up. These replacements locate the filler at the highest point to bleed off air on cars with low-mount radiators. The filler necks can be located on either the left or right side of the vehicle. They include 1/2 in. NPT fittings for the installation of a water temperature sending unit, and two 1/4 in. NPT fittings for return lines on popular aftermarket cylinder heads.
