Fuel-system work on a 1980 CB750C can involve the tank fitting, individual carburetors or the airbox. Identify where the repair is needed before buying a rebuild package. Replacement tanks and custom filters also change the checks needed before trusting an original-style application.

1980 Honda CB750C · Fuel System Parts Buying guide
Work from the tank connection to the intake
The 1980 petcock uses an M16 × 1.5 thread, carb repair kits service one carburetor, and the stock-type filter belongs to the original airbox arrangement.
The sealing repair kit contains a float bowl gasket, float needle and O-rings for one carburetor. A kit with jets covers a different scope. Inspect the carburetors and compare contents before ordering enough packages for the planned work.
Tank and intake changes matter
The featured petcock is a 1980 application with a specified thread; compare a changed tank directly. The stock-type air filter and 54mm pod filters serve different intake arrangements, so choose for the motorcycle as configured rather than by model year alone.
Fuel System Parts questions
Does one carb kit rebuild all four carburetors?
No. The featured repair kit services one carburetor. Select quantity according to the number being rebuilt, and compare the included parts with the work planned for the rack.
Will the 1980 petcock fit a replacement tank?
Only after the actual tank connection is checked. The featured petcock uses M16 × 1.5 threads; a changed or aftermarket tank may have a different fitting.
Are pod filters replacements for the airbox element?
They are a different intake arrangement. The stock-type filter fits the listed airbox application, while a pod clamps to a compatible carburetor inlet and needs configuration-specific checks.
