1981 Honda CB900F Petcocks & Tank Hardware

For the 1981 CB900F fuel tank, compare the M18 x 1.0 petcock, separate cap seal and front or rear support rubbers by the problem being repaired. A replacement tank can change the connection, so confirm the fitted thread and mounting arrangement rather than relying on year alone.

1981 Honda CB900F Supersport · Tank Parts Buying guide

Check the tank connection and supports

The petcock has a year-specific 1981 application. The rear holder rubber references 17613-438-000, while the front cushions are separate sold-each parts with two specified per motorcycle.

A changed tank needs a fresh match

The listed 1981 petcock uses M18 x 1.0 threads. Check the fitted tank, outlet and lever clearance before ordering. The rear support listed here references 17613-438-000 and explicitly names the 1981 CB900F; inspect it separately from the two front cushions.

Inspect tank support and cap condition separately

Check the front cushions, tank mounting channels and rear support while access is available. A cap seal cannot correct a bent sealing rim, damaged latch or rusty tank neck. Confirm that the cap vents as designed, and leak-test any fuel-system repair safely before riding.

Buying questions

Can the petcock be selected from model year alone after a tank swap?

No. Measure the actual connection and compare its sealing arrangement, outlet direction, hose size and lever clearance. The 1981 listing specifies M18 x 1.0; the 1982 listing specifies M20 x 1.0. Neither year proves the thread on a replacement tank.

Will a new cap seal fix any leak around the filler?

Inspect the cap rim, hinge, latch and tank neck for damage or corrosion as well as the rubber. Confirm that the cap vents correctly. A seal-only part cannot correct a distorted cap or sealing surface.

What should be checked after fitting a replacement petcock?

With appropriate fuel-handling precautions, verify valve operation and check the tank joint, valve body and hose connections for leakage before riding. Use fuel-compatible hose and seals, and investigate any leak before returning the motorcycle to service.

Not sure which part you need?

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