The Honda 16853-Z2E-000 Auto Fuel Petcock Air Cleaner Tube is a genuine OEM component designed for GX440 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a correct, trouble-free installation. Confirm your engine's serial number against the fitment table before ordering, as Honda updates parts at serial number breaks and the right tube for your unit depends on where yours falls in the production run.
Key Features
- Genuine Honda OEM Construction — manufactured by Honda to match the original tube's dimensions and material exactly, so fuel and air routing behave as designed from day one
- Direct-Fit for GX440 Engines — engineered specifically for the GX440 horizontal shaft engine, connecting the auto fuel petcock to the air cleaner without modification
- Serial Number Matters — Honda revises parts at production breaks, so cross-reference your GX440 engine serial number with the fitment table to confirm this is the correct tube for your unit
- Fuel Flow Integrity — a cracked, hardened, or collapsed tube disrupts the vacuum signal that controls the auto petcock, causing flooding, fuel starvation, or hard starting; this replacement restores normal operation
The auto fuel petcock on GX440 engines is a vacuum-operated valve that controls fuel delivery from the tank to the carburetor. A small vacuum signal — drawn through a tube connected to the air cleaner side — opens the petcock when the engine is running and closes it automatically when the engine stops, preventing carburetor flooding and fuel leaks during storage. The Auto Fuel Petcock Air Cleaner Tube is the conduit that carries this vacuum signal. When the tube cracks, hardens with age, or collapses internally, the vacuum signal is lost, and the petcock may fail to open fully — starving the engine of fuel — or fail to close — allowing raw fuel to flood the carburetor. Replacing a degraded tube restores the precise vacuum routing the system depends on.
