Multiquip EM11418 Cap with Gauge "Fuel" (10.5")

The Multiquip EM11418 Cap with Gauge "Fuel" (10.5") is a genuine OEM replacement designed for Multiquip and Whiteman ride-on power trowels including the HHN31V, HTX44, STX55, HTN, JWN, STH, and HTH series. As a direct OEM part, EM11418 is produced to the same specification as the original component installed at the factory, ensuring a correct, trouble-free installation. DHS Equipment supplies this part with full confidence in fitment accuracy across the applicable trowel families listed above.

Key Features

• OEM-Spec Sealing and Venting: — Engineered to the original material and thread specification, ensuring the cap seals and vents the fuel tank correctly without leaks or pressure buildup.
• Integrated Fuel Gauge: — The built-in 10.5" gauge allows operators to read fuel level at a glance without removing the cap, supporting continuous workflow on the slab.
• Direct-Fit Replacement: — Designed to thread directly onto the fuel tank filler neck of compatible Multiquip ride-on trowel models with no modification to the tank or surrounding hardware.
• Broad Trowel Family Coverage: — Fits mechanical, hydrostatic, and heavy-duty ride-on trowel models including HHN31V, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STH, HTH, JWN, and HTN series.
• Fuel System Integrity: — A worn or cracked fuel cap can allow contamination into the tank or cause fuel to escape during operation; replacing with a genuine OEM cap maintains a clean, closed fuel system.

The fuel cap with gauge serves two critical functions on a ride-on power trowel: it seals the fuel tank to prevent spillage and contamination, and its integrated gauge allows the operator to monitor fuel level without stopping work to remove the cap. The 10.5" gauge length positions the indicator where it can be read easily during operation. When a fuel cap seal deteriorates or the gauge fails, the operator loses visibility into remaining run time and risks fuel contamination — both of which can interrupt a concrete finishing pour at a critical stage. Replacing the cap with a correct OEM unit like the part restores both the seal integrity and the fuel level monitoring function.
