1972 Honda CB350F0 Tank Caps & Petcock Parts

Tank work on the CB350F0 may call for a sealing rubber, a cap latch or the original petcock’s body seal. Check the fitted tank and tap first, then compare complete cap contents with separate latch hardware so the order matches the actual fault.

1972 Honda CB350F0 · Tank Caps & Petcock Parts Buying guide

Separate cap repairs from petcock sealing work

A hinged filler cap and its latch use different hardware, while the petcock body O-ring seals a separate joint below the tank. Original and replacement taps need to be identified before ordering small service seals.

Choose a cap, latch or rubber repair

The chrome cap includes its gasket, hinge pin and E-clip. The separate chrome latch supplies the latch, return spring, mounting pin and C-clip. If the cap and latch remain serviceable, the linked rubber seal offers a narrower repair; inspect the hinge and latching surfaces before deciding.

Match petcock seals to the actual tap

The featured body O-ring is specified for an original Honda petcock, not an aftermarket replacement tap. The linked petcock gasket and screen are separate service pieces with different purposes. Compare the existing tap and leaking joint before disassembly so a similar-looking seal does not become an assumed substitute.

Tank Caps & Petcock Parts questions

Does the chrome tank cap include its latch?

The chrome cap includes a gasket, hinge pin and E-clip; the latch assembly is sold separately. The separate latch kit includes its return spring, mounting pin and C-clip, so choose according to the hardware already on the tank.

Will the original-petcock body O-ring fit an aftermarket tap?

It is specified for the stock Honda petcock. Identify an aftermarket tap by its manufacturer and sealing arrangement before ordering a seal; the motorcycle’s model tag alone does not establish compatibility with a replacement tap.

Can I replace only the fuel-cap seal?

A separate rubber seal is available for the listed cap application. Check that the cap body, hinge and latch are still sound and compare the fitted design, especially if the tank or cap has been replaced.
