1968 Honda CL350K0 · Tank Caps & Fuel Taps Buying guide

Let the fitted tank determine its replacement parts

The petcock has a specified thread, the chrome cap includes a gasket, and the mounting rubber serves the rear tank support. Compare each fitting with the tank on the motorcycle rather than assuming one match settles them all.

Choose between a cap and a sealing repair

The chrome filler cap comes with a gasket installed. If you intend to retain the existing cap, compare the separately linked rubber seal with its sealing arrangement. Check the cap attachment and tank sealing surface before deciding whether a cap or seal-only order addresses the repair.

Check the replacement tank at every interface

After a tank change, verify the M16 × 1.5 tap connection and compare the outlet and lever clearance. Check the rear support separately against the tank-holder rubber. Matching the tap thread does not establish that the cap and mounting pieces suit the same tank.

Buying questions

Does the chrome tank cap need a separate gasket?

The chrome cap is supplied with a gasket installed. Compare the cap attachment and tank sealing surface before ordering, and avoid duplicating the separate seal unless your repair plan requires it.

What should I check before ordering the petcock?

Verify the tank connection is M16 × 1.5 and compare the outlet arrangement and operating clearance. A changed tank needs its own compatibility check even if the motorcycle’s model is unchanged.

Can I replace just the cap sealing rubber?

A separate replacement cap seal is linked. Compare it with the retained cap’s seal profile and inspect the cap attachment and sealing surface before choosing a seal-only repair.
