Honda CB Fuel Tanks, Caps & Petcock Parts

The fuel tank, filler cap and petcock work together to store fuel securely and control its delivery to the carburetors. Aging cap seals, petcock gaskets, mounting rubbers and internal screens can deteriorate over time. Replacing worn components helps maintain dependable fuel control and secure tank mounting on a vintage Honda CB motorcycle.

This collection includes model-specific fuel petcocks, OEM-style filler caps, rubber cap seals, cap latches, petcock screens and gaskets, mounting rubbers, fasteners and related fuel-tank hardware. Petcock thread sizes, outlet arrangements, cap styles and mounting components vary between Honda CB models and production years. Compare the specifications and OEM reference listed on each product page when selecting replacement parts.

Complete the fuel-delivery system with our Honda CB fuel lines and filters and fuel-line hose clamps. For carburetor service components, browse carburetor rebuild and jetting parts. You can also personalize or restore the tank’s exterior with our Honda CB gas-tank decals. Use the My Motorcycle selector to display fuel-tank and petcock parts listed for your Honda CB model and year.
