Key Features
- Genuine OEM Fuel Delivery Spec — Built to the original output pressure and flow rate required by the engine on STX and HTX series trowels, maintaining proper fuel delivery at all throttle positions.
- Direct-Mount Replacement — Matches the original mounting configuration and inlet/outlet orientation, dropping into place without modification to fuel lines or bracketry.
- Confirmed Fitment — Engineered for STX55J6, STXD6i, HTXD6i, and STX55Y6 Whiteman ride-on power trowels; always cross-reference your model code before ordering.
- Supersession Notice — Part number 11922552102 is no longer active (NLA); the current replacement part number is 21741. Both reference the same OEM Fuel Pump application.
- Protects Engine Performance — A correctly functioning fuel pump maintains consistent fuel pressure to the carburetor or injector, preventing hard starts, rough idle, and power loss under load during finishing operations.
A fuel pump is responsible for drawing fuel from the tank and delivering it at the correct pressure and volume to the engine's fuel system. On ride-on trowels like the STX and HTX series, consistent fuel delivery is critical — any drop in pressure can cause the engine to surge, lose power, or stall mid-pour, disrupting finishing work. When a fuel pump weakens or fails, symptoms typically include difficulty starting, engine hesitation under load, and erratic throttle response; replacing it promptly restores stable engine operation.
