Key Features
- Genuine OEM Fuel Delivery Spec — Matched to the MQC-100's engine fuel system requirements, ensuring correct flow rate and pressure output for consistent pump operation.
- Direct OEM Replacement — Engineered to mount in the same position as the original unit, using the existing fuel line connections on the MQC-100.
- Confirmed MQC-100 Fitment — Verified for the Multiquip MQC-100 concrete pump; use part number 4175474 to confirm accuracy before ordering.
- Sustained Engine Performance — A functioning mechanical fuel pump maintains steady fuel flow to the engine under load; a worn pump causes hard starts, rough running, and output loss on the concrete pump.
- Fuel System Integrity — OEM construction ensures diaphragm material and valve seating are compatible with the fuel system on this engine, reducing the risk of fuel leaks at the pump body.
A mechanical fuel pump draws fuel from the tank and delivers it to the carburetor or injection system using a diaphragm driven by the engine's camshaft or crankcase pulses. On a concrete pump like the MQC-100, consistent fuel delivery is critical — any drop in pressure or flow will cause the engine to starve under load, resulting in power loss or stalling mid-pour. When the diaphragm cracks or the internal check valves wear, fuel delivery becomes erratic and the engine will struggle to maintain the output needed to move material through the pump.
