Multiquip 43140-09 LPG Vapor Regulator - OEM Replacement Part for Dual Fuel Trowels

The LPG vapor regulator controls propane flow from the liquid propane gas tank to the engine on dual fuel ride-on trowels, enabling seamless fuel system switching without interrupting operation. This component is critical for the STXDF's dual fuel capability, which allows operators to switch between gasoline and liquid propane (LPG) using the digital control panel while maintaining continuous operation.

Designed specifically for use with HD-5 type liquid propane systems, this vapor regulator ensures proper fuel delivery to Briggs & Stratton engines equipped for propane operation. The STXDF dual fuel system holds 33.5 lb. (15.2 kg/36.3 liters) of liquid propane and is approved for indoor use where proper ventilation is maintained. The regulator works in conjunction with the propane shutoff valve to provide safe, reliable fuel management during concrete finishing operations.

When shutting down LPG mode, operators turn the propane shutoff valve clockwise until closed after turning the ignition key to the OFF position. Proper regulator function is essential for maintaining consistent engine performance and preventing fuel delivery issues during critical finishing work.
