Part: Gas Cap Seal for Honda CB350 / CL350 / SL350 / CB350F / CB360 / CL360 / CB400F / CB450 / CB500T / CB500F / CB550 / CB750
Why You Need This Part: You might not have even realized that there was a seal there. It usually has more cracks and wrinkles than a plumbers convention. Finish the tank off right and protect the paint with a new seal. When this seal is old and cracked it is common for gas to splash out even when the cap is closed. This gas cap seal fits a wide range of the late 60's and early 70's Honda CB and CL motorcycles. It primarily fits the flip-top style gas cap rather than the twist-off gas cap found on earlier vintage Honda motorcycles. see the fitment chart below to confirm.
Installation Tip: The seal is more than just a flat rubber ring, it is actually fits over the tank stopper like the rings of Saturn. Make sure to install the ring so that when the gas cap is closed, the thicker side of the ring faces the opening of the gas tank. Takes a little work to get it in place, be patient.
