Multiquip 43140-05 Gasoline Fuel Block - OEM Replacement Part

The gasoline fuel block is a critical fuel delivery component that regulates and distributes fuel flow from the tank to the engine on gasoline-powered ride-on trowels. This assembly ensures proper fuel metering and supply during operation, preventing fuel starvation that can cause engine hesitation, stalling, or rough running. Technicians replacing this component should ensure the trowel is secured on a level surface with the engine stopped and cooled before beginning work, and should inspect fuel lines and connections for wear or damage during installation.

When troubleshooting fuel delivery issues, check if the fuel cock opens properly and verify that fuel is present at the carburetor. Apply lubricant to loosen the fuel cock lever if it does not operate smoothly, or replace the fuel block assembly if necessary. Always wipe up any spilled fuel immediately during replacement to prevent fire hazards, and never smoke around or near the equipment during service.

This fuel block is compatible with the following Multiquip trowel models:

• PRX Series Trowels
• STXDF Ride-On Trowels
