1973 Honda CB350G · Tank Caps, Taps & Mounts Buying guide

Match the tank fittings rather than the paintwork

A tank can look appropriate for the motorcycle yet use different fittings. Compare its cap hinge, latch, petcock threads and rubber mounting points before choosing which parts to renew.

Check exactly what the cap supplies

The chrome cap includes its gasket, hinge pin and E-clip. The linked chrome latch assembly is a separate choice containing its latch, return spring, mounting pin and C-clip. Inspect the tank-side fittings before deciding whether the cap, latch or seal needs replacement.

Choose mounting rubber by position

The featured rear holder rubber supports the rear mounting arrangement. Front tank cushions are different parts, including a linked aftermarket option sold individually. Check the actual mount shapes and count the positions being renewed, particularly on a changed or custom tank.

Buying questions

Does the chrome fuel cap include its gasket?

Yes. The cap includes a gasket, hinge pin and E-clip. The latch assembly is separately offered, so inspect the existing latch before deciding whether to add it.

Will the petcock fit an aftermarket tank?

Only after the tank connection is checked against M16 × 1.5 threads and the outlet route has suitable clearance. Do not assume a swapped tank uses the original fitting.

Are the front and rear tank rubbers interchangeable?

No. They serve different mounting positions. Compare the rear holder and front cushions separately and order the parts that match the actual tank supports.

Not sure which part you need?

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