1978 Honda CB750F · Tank, cap & petcock parts Buying guide

Choosing fuel tank parts

Match the tank connection, filler cap or mounting position before ordering. The replacement tap has an outlet difference worth planning for, while the cap, emblems and cushions have separate package contents.

Emblems and attachment clips

The emblem is sold individually with two attachment clips already included.

Tank cushion positions

Front cushion 02-6534 replaces 17611-283-010; rear cushion 02-6536 replaces 17613-399-000. Both are listed for the 1975–78 CB750F.

Tank part questions

Does this replacement petcock have the original F outlet direction?

Petcock 20-8037 is offered as an alternative to the discontinued stock type. Its outlet faces right rather than back or down on the CB750F. Check hose clearance as well as the M16 × 1.5 tank thread before ordering.

Should I add a cap seal when buying the complete filler cap?

Cap 73-0079 already has its rubber gasket installed, but does not include an attached chain. Seal 20-0097 is a separate option for seal-only work and replaces 17631-329-003; identify the cap being retained before choosing that repair.
