The Multiquip 17620Z4H000 Tank Cap is a genuine OEM fuel tank cap designed for GX120UT1-series Honda engines (S/N to ) fitted to CA4HM, MVC82VHW, MVC82VH, and J36-M30 equipment. As a factory-original component, it meets the exact design and material specifications set by the original manufacturer, ensuring a proper seal and correct venting behavior on every machine it covers. This Tank Cap is sourced directly through Multiquip's authorized parts channel and carries the same part number — 17620Z4H000 — used by dealers and service technicians worldwide.
Key Features
- OEM Sealing Integrity — Engineered to the original compression and thread specification for the GX120UT1 fuel tank, preventing fuel leaks and maintaining a proper pressure-venting cycle.
- Thread-Matched Direct Replacement — Threads directly onto the factory fuel tank neck with no fitting adjustments needed, matching the original cap's diameter and pitch exactly.
- Broad Equipment Coverage — Fits CA4HM walk-behind trowels, MVC82VHW and MVC82VH plate compactors, and J36-M30 walk-behind trowels, covering multiple machine types from a single part number.
- Engine Serial Number Specific — Validated for GX120UT1QX2 engines within the S/N range 1120059 to 1188057, so you can order with confidence that this is the correct cap for your specific engine build.
- Fuel System Safety — A correctly sealed tank cap prevents fuel vapor escape and debris ingestion into the tank — both of which can lead to engine contamination or fuel system faults over time.
The fuel tank cap seals the opening of the engine's fuel tank, keeping fuel contained while allowing controlled venting so the tank does not build up negative pressure as fuel is consumed. When a tank cap fails — through a cracked body, worn threads, or a degraded seal — it can allow fuel to leak during operation or let dirt and moisture enter the tank, leading to carburetor contamination and hard-starting conditions. Replacing a worn or damaged cap with the correct OEM unit restores proper fuel system containment and keeps the engine running cleanly.
