The Honda 16198-ZJ1-840 Drain Tube is a genuine OEM component designed for GX610, GX620, GX630, GX660, GX670, and GX690 horizontal shaft engines, GXV610, GXV620, and GXV670 vertical shaft engines, and EB10000 and EB11000 generators. As a direct Honda OEM part, this drain tube is manufactured to the same specifications as the original, ensuring a proper fit without any adaptation. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks across these engine families.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this drain tube meets the same specifications as the part that left the factory, so there are no concerns about dimensional mismatches or material substitutions.
- Broad Fitment Across Honda's Big-Block Lineup — covers GX610, GX620, GX630, GX660, GX670, and GX690 horizontal shaft engines; GXV610, GXV620, and GXV670 vertical shaft engines; and EB10000 and EB11000 generators.
- Check Your Serial Number — Honda's large-displacement engine families span multiple production runs, and part fitment can change at serial breaks. Verify your unit's serial number against the compatibility table to confirm this is the correct drain tube for your machine.
- Proper Drainage When It Counts — a cracked, kinked, or deteriorated drain tube can allow fuel or float-bowl residue to pool rather than drain cleanly, creating a fire hazard and making carburetor service messier and more difficult.
The drain tube routes fuel and accumulated residue away from the carburetor float bowl during service or when the drain screw is opened — a necessary step before carburetor removal, extended storage, or winter preparation. Keeping this passage open and leak-free means fluids exit where they should and do not contact hot engine surfaces or collect in enclosed spaces. When the tube cracks, hardens, or pulls loose from its fitting, drainage becomes uncontrolled, increasing the risk of a fuel spill and complicating routine maintenance.
