1972 Honda CB350K4 · Tank Caps & Petcocks Buying guide

Choose cap coverage and tank hardware together

The chrome cap and matte-black assembly have different included hardware. The petcock requires the correct tank connection, while front and rear rubbers address mounting rather than fuel sealing.

Parts to consider

Decide whether the latch needs replacement

The chrome cap includes a gasket, hinge pin and E-clip. The linked matte-black assembly additionally specifies its latch, spring, mounting pin and C-clip. Compare what can be reused on your tank before choosing a package or ordering a separate latch.

Separate fuel sealing from tank support

The linked cap rubber seal references 17534-323-300, which Honda identifies for the K4. Front and rear tank rubbers serve a different job: locating and supporting the tank. Check their shape and condition separately, particularly if the tank has been changed or its mounts modified.

Buying questions

Will the petcock fit an aftermarket tank?

Only if the tank has the specified M16 × 1.5 connection and suitable clearance and hose routing. The motorcycle model alone cannot establish the fittings on a non-original tank.

Does the chrome cap include a new latch?

Its stated contents are the cap, gasket, hinge pin and E-clip. The linked matte-black assembly explicitly includes a complete latch arrangement, so choose according to the hardware you need to renew.

How many front cushions are in one purchase?

The aftermarket front cushion is sold individually. Order two if replacing both front tank cushions, and inspect the separate rear holder rubber instead of assuming it is included.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
