1971 Honda CB350K3 Fuel Tank Parts

Check the tank fitted to your 1971 CB350K3 before selecting a cap, latch or petcock. Chrome and matte-black cap choices include different hardware, and the replacement fuel tap needs an M16 × 1.5 connection. Inspect the cap seal and tank supports at the same time.

1971 Honda CB350K3 · Tank Caps, Mounts & Petcocks Buying guide

Match the cap assembly to the repair and finish

Choose a complete cap only when the repair calls for it. Separate seals and latches can address smaller problems, while the petcock and mounting rubbers need their own checks against the tank actually installed.

Compare the supplied cap hardware

The chrome cap includes a gasket, hinge pin and E-clip. The matte-black cap includes those items plus a latch assembly. The linked chrome latch supplies the latch, return spring, mounting pin and C-clip separately, allowing the order to follow the actual repair.

Inspect the tank beyond the cap

A fuel tap must match the tank connection, so verify the M16 × 1.5 mm thread and outlet clearance before ordering. Check the mounting supports too. The linked rear holder rubber serves a different mounting location from the separate front tank cushions.

Buying questions

Which cap includes a complete latch assembly?

The matte-black cap includes the latch, spring, mounting pin and C-clip, along with the cap, gasket and hinge hardware. The chrome cap supplies gasket and hinge hardware; its chrome latch is offered separately.

Can I replace just the seal on the existing cap?

The linked rubber seal has a specific 1971 CB350K application. Compare the existing cap and seal profile first, especially if the cap has been replaced with another style or the tank is not original.

Will the petcock work with a replacement tank?

Only choose it after confirming an M16 × 1.5 mm tank connection and suitable outlet clearance. Compare the installed tank directly; the motorcycle’s model year cannot confirm an aftermarket tank’s fitting.

Not sure which part you need?

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