Fuel Neck Grommet

This fuel neck grommet is a fully molded rubber seal designed to fit the filler neck opening on 1934-1935 Cadillac 355 D 4-Door Sedans and Convertible Sedans. It measures 4-3/8" outside diameter, 2-3/16" inside hole diameter, and 5/8" height, fitting filler necks sized between 2-1/8" and 2-1/4". The flat bottom includes a slight ridge for a secure fit, helping prevent fuel leaks and keeping dirt and moisture out of the tank.

Installation is straightforward: simply press the grommet into the fuel filler opening, ensuring the ridge seats firmly to create a tight seal. This durable rubber piece helps maintain your vehicle’s fuel system integrity and preserves that classic ride.
