Fuel Neck Grommet

This fuel neck grommet is molded with a slight angle to fit snugly around the fuel filler neck on various 1941-1948 Chevrolet Business Coupes, pickup trucks, and panel vans. It measures 4-1/4" outside diameter, 2-1/8" inside hole diameter, with a tapered height of 7/8" front and 1-1/4" back. This part replaces the original factory grommet #3658166, providing a proper seal to prevent fuel leaks and protect against debris entering the tank.

Installing this grommet is straightforward: remove the old, cracked gasket from the filler neck opening, then press this new grommet into place, ensuring the angled side matches the contour of the filler neck. It’s a quality replacement designed to maintain the integrity of your classic Chevy’s fuel system.
