1969 Honda CB450K · Gas Tanks, Caps, Petcocks & Parts Buying guide

Choose tank parts from the fitting being retained

The chrome cap includes an installed gasket, while the separate rubber seal serves a retained cap. The fuel tap has M16 × 1.5 threads. Front cushions are sold each, with two stated per motorcycle; these are distinct selection and quantity checks.

Compare a seal repair with a complete cap replacement

The chrome filler cap comes with its gasket already installed. The separate seal references Honda 17631-329-003 and is intended as a seal component. Inspect the cap you plan to retain before deciding which purchase fits the repair; do not add a separate seal solely because a new cap is being ordered.

Check altered tanks directly

The petcock description specifically asks for a thread-size check. Use the outlet on the tank you will fit, even when the motorcycle year appears in the application list. Mounting cushions also need comparison with the retained mounting points; their two-per-bike count does not describe every rubber support around the tank.

Choosing parts for your CB450K repair

Is a separate cap seal needed with the complete chrome cap?

The cap description states that its gasket is installed. A separate seal is a different repair choice for a cap you intend to keep. Confirm the existing cap and seal pattern before choosing the standalone rubber seal.

What if the tank has been replaced during restoration?

Check the replacement tank’s filler arrangement, outlet thread and mounting points directly. The M16 × 1.5 petcock specification is a check to perform on that tank. Original model-year fitment cannot establish the fittings used on an altered tank.

Does one front-cushion order cover both mounting points?

The cushion is explicitly sold each, and the application states two used per bike. Order two to renew both front positions. Its reference 17611-283-010 identifies the front cushion; it is not a complete set of every tank mounting rubber.

Not sure which part you need?
