1982 Honda CB750SC Tank Caps & Petcocks

Tank-related fuel problems can involve the cap, threaded petcock or separate automatic shut-off valve on the 1982 CB750SC. Identify the affected component before ordering. Replacement tanks deserve particular attention because their cap opening and petcock thread may differ from the original arrangement.

1982 Honda CB750SC · Tank Caps & Petcocks Buying guide

Identify which tank fitting needs repair

The petcock uses M20 × 1.0 threads. The replacement cap includes its gasket and two keys. A separate sealing kit services the automatic shut-off assembly rather than replacing the tank-mounted petcock.

Confirm a changed tank’s fittings

A replacement tank can change the threaded petcock connection, outlet position or cap fit. Compare the actual tank with the featured M20 × 1.0 petcock and allow room for the outlet and hose routing. The motorcycle year by itself cannot verify an aftermarket tank.

Separate the two fuel-control assemblies

The automatic shut-off repair kit supplies sealing components for that separate valve. Its description notes that one included O-ring may not be used in every configuration. Identify the assembly and use its service information rather than trying to use every piece in the package.

Tank Caps & Petcocks questions

Will the petcock fit an aftermarket tank?

Check for an M20 × 1.0 threaded connection, suitable outlet position and clearance. A swapped tank may use another fitting, even when mounted on an otherwise original 1982 CB750SC.

Does the replacement cap come with keys?

Yes. The original-type cap includes a gasket and two keys. Compare the tank opening and locking arrangement before ordering if the tank or filler has been changed.

Why might the shut-off kit have an unused O-ring?

The product covers configurations where one supplied O-ring may not be required. Match the actual automatic shut-off assembly and its instructions; do not add an extra seal simply because 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.
