Multiquip 11922 Tank Fuel 12 Gallon Polyethylene

The Multiquip 11922 Tank Fuel 12 Gallon Polyethylene is a genuine OEM fuel tank designed for STX and HTX series hydrostatic ride-on power trowels, including the STX55J6, STXD6i, HTXD6i, and STX55Y6. As a direct OEM replacement sourced through Multiquip's authorized parts network, this tank is built to the same specifications as the original component installed at the factory. Its 12-gallon polyethylene construction provides the fuel storage capacity these machines require to sustain extended concrete finishing operations. Confirm your model code against the fitment list before ordering to ensure correct application.

Key Features

• Genuine OEM Construction — Polyethylene material matches the original tank's chemical resistance profile, standing up to prolonged fuel contact without degradation or permeation issues.
• 12-Gallon Capacity — Maintains the full fuel reserve these hydrostatic ride-on trowels depend on for uninterrupted finishing runs on large concrete pours.
• Direct OEM Replacement — Mounts in the original tank position using existing hardware and fittings, keeping the installation straightforward for experienced technicians.
• Broad STX/HTX Series Fitment — Confirmed for STX55J6, STXD6i, HTXD6i, and STX55Y6 hydrostatic ride-on trowels; verify your model code before ordering.
• Fuel System Integrity — A cracked, leaking, or degraded tank introduces fuel supply inconsistency and creates a serious fire hazard on an active jobsite; replacing with a genuine OEM unit restores safe, reliable fuel delivery.

The fuel tank stores the onboard supply of gasoline or diesel that feeds the engine powering the machine's hydraulic drive and blade control systems. On hydrostatic ride-on trowels like the STX and HTX series, consistent fuel delivery is essential — any interruption caused by a damaged or leaking tank can stall finishing operations mid-pour, where timing is critical. A tank that has cracked, warped, or developed leaks at its fittings should be replaced promptly to maintain both machine performance and operator safety.
