1976 Honda CB550F · Tank Taps, Seals & Mounts Buying guide

Separate fuel-control parts from tank mounting parts

Check the fitted tank before ordering, particularly when it has been replaced or modified. The model application is a starting point; tap threads, cap shape and cushion locations still matter.

Parts to consider

Check the tap reference and fitting together

The featured tap replaces 16950-374-671 and provides on, off and reserve operation. Another tap in this category replaces 16950-341-671 and specifies M20 × 1.5 threads. Compare the original reference, actual tank connection and clearance; a shared year application does not prove that different taps interchange.

Count cushions by their mounting position

The front cushion rubber is sold individually and the application uses two. The linked rear rubber is a different shape and reference, 17613-286-000. Inspect front and rear supports separately rather than expecting a front-cushion order to renew the entire tank mounting arrangement.

Your buying questions

How should I choose between the two listed fuel-tap references?

Compare the fitted tap reference and actual tank connection. The featured tap replaces 16950-374-671; the other listed tap replaces 16950-341-671 and specifies M20 × 1.5 threads. Match those details to the fitted tank rather than assuming a shared year application makes the taps interchangeable.

Is one front tank cushion a pair?

No. The front rubber is sold individually, although two are used per motorcycle. Order two for a complete front-cushion replacement, or the smaller quantity required for a limited repair.

Can a cap seal fix every fuel-tank leak?

The cap seal belongs at the filler cap. Fuel escaping at a tap connection or elsewhere on the tank calls for a different assessment. Identify where fuel is escaping before choosing a cap seal or replacement tap.
