1978 Honda CB400A — Alimentation en carburant

For the 1978 Honda CB400A, separate tank-supply faults from carburetor and intake service. A petcock, manifold O-rings and an air filter work at different points in that system. Identify the fitted tank, carburetors and airbox before choosing replacement parts.

1978 Honda CB400A · Fuel & Intake Buying guide

Trace the purchase from fuel tank to airbox

The available parts cover fuel supply, carburetor service and intake sealing. Keep each repair location clear, and check any changes to the tank or airbox before treating a stock-type replacement as the right choice.

Parts to consider

Start with the component that is leaking or worn

A tank-valve leak, a float-bowl leak and a worn intake seal require different parts. Locate the fault before combining purchases. If the tank or carburetors have been replaced, identify those assemblies directly rather than relying only on the motorcycle’s year and model.

Keep the original intake arrangement in view

The featured filter replaces reference 17211-413-000 for the stock-type application. The manifold O-rings are a four-piece pack for a different sealing location. Compare the existing airbox and intake joints so the order covers the parts your CB400A actually retains.

Fuel & Intake questions

Will the petcock fit an aftermarket tank?

Only if the tank connection and layout are suitable. The listed valve uses an M16 × 1.5 thread; compare the connection, outlet position and clearance on the changed tank before ordering.

How many intake O-rings are supplied in the set?

The set contains four 40 × 2.6 mm O-rings for the manifold-to-cylinder-head joints. Count the positions being serviced separately; package quantity does not establish how many rings your repair requires.

Is the stock-type air filter suitable for individual pod filters?

It is intended for the original-type air-filter application. A pod-filter conversion uses different mounting and sizing checks; identify the fitted intake system before choosing its replacement filter.
