1973 Honda CB350F0 Fuel Caps & Tank Mounts

Inspect the tank cap, latch and rubber seal before deciding how much to replace on your 1973 CB350F0. Chrome and matte-black caps have different package contents, while separate latch parts and front mounting cushions let you address a more focused tank repair.

1973 Honda CB350F0 · Fuel Caps & Tank Mounts Buying guide

Choose cap parts by the fault and finish

A sound cap can need only a seal or latch repair. A damaged cap may justify a complete replacement. Compare the hinge and latch on the fitted tank, then check which small components come with the selected cap.

Compare complete-cap contents

The chrome cap includes a gasket, hinge pin and E-clip. The matte-black assembly also includes the latch, return spring, mounting pin and C-clip. Choose according to the condition of the existing latch so the order contains the parts needed for the repair.

Check the tank supports too

The linked aftermarket front cushion replaces the original front tank mounting rubber and is sold individually. Count the supports being renewed and compare the rubber shape, especially with a changed tank. A cap repair and a loose or hardened tank mounting rubber are separate jobs.

Common questions

Which cap includes the latch assembly?

The featured matte-black cap includes the latch, return spring, mounting pin and C-clip as well as the cap’s hinge hardware and gasket. A separate chrome latch assembly is linked for a focused repair.

Can I replace the rubber seal without replacing the cap?

A separate replacement seal is available for the matching original-style cap. Inspect the cap and tank sealing face first; damage or an incorrect cap may need a broader repair than a new rubber seal.

Are front tank cushions supplied as a pair?

The linked aftermarket cushion is sold individually. Order two when replacing both matching front supports, and compare the existing mount shape if the tank or frame fittings have been changed.

Not sure which part you need?

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