Multiquip 43759 8" Fuel Sending Unit

The Multiquip 43759 8" Fuel Sending Unit is a genuine OEM component designed for PRX series ride-on power float equipment. This is a direct OEM replacement sourced through Multiquip's authorized parts network, ensuring the correct sender depth, float travel, and resistance range for the PRX fuel system. Fits PRX hybrid ride-on trowel models — verify your model number before ordering to confirm application compatibility.

Key Features

• OEM-Calibrated Resistance Range — Genuine Multiquip part engineered to match the exact ohm sweep required by the PRX fuel gauge, so readings are accurate across the full tank level.
• Correct 8" Sender Depth — The 8" unit length is specific to the PRX tank depth, ensuring the float reaches full travel without binding at the top or bottom of the tank.
• Direct OEM Replacement — Mounts to the existing fuel tank flange using the original hardware pattern, requiring no modification to the tank or gauge wiring.
• PRX Series Fitment — Designed specifically for Multiquip PRX hybrid ride-on power float equipment; always confirm your model against part number 43759 before ordering.
• Fuel Level Accuracy — A failed or worn sending unit causes erratic or dead gauge readings, creating the risk of running the machine out of fuel mid-pour; replacing it restores dependable fuel monitoring.

The fuel sending unit is a sensor mounted inside the fuel tank that tracks the fuel level and transmits that information to the gauge on the operator console. It works through a float connected to a variable resistor — as the fuel level drops, the float moves and changes the resistance signal sent to the gauge. When the sending unit fails or corrodes, the gauge may read full, empty, or fluctuate erratically regardless of actual fuel level, leaving operators without reliable information during operation. Replacing the unit with a correctly spec'd OEM part restores accurate, consistent fuel level monitoring.
