Key Features
- Genuine OEM Voltage Match — Rated at 12 Vdc to meet the exact electrical and fuel delivery specification required by the HTN27K and HTN28K engines.
- Direct Drop-In Replacement — Engineered to the same mounting configuration and port sizing as the original pump, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for use on Multiquip HTN27K and HTN28K mechanical ride-on power trowels.
- Consistent Fuel Delivery — A properly functioning fuel pump maintains steady fuel pressure to the engine, supporting smooth throttle response and consistent trowel blade speed during finishing passes.
- Fuel System Integrity — Using the correct OEM pump prevents pressure mismatches that can cause hard starting, rough idle, or unscheduled engine shutdowns during operation.
The fuel pump is responsible for drawing fuel from the tank and delivering it at the correct pressure to the engine's carburetor or fuel system. On a ride-on power trowel like the HTN27K and HTN28K, consistent fuel delivery is critical to maintaining steady engine speed across varying blade loads during concrete finishing. When a fuel pump weakens or fails, the engine may start hard, run erratically, or stall under load — interrupting the finishing window and potentially affecting the quality of the concrete surface.
