Multiquip EE60373 Remote DEF System Pump Assembly

The Multiquip EE60373 Remote DEF System Pump Assembly is a genuine OEM component designed for MQ Power Fuel and DEF Tank systems, specifically the DEFTANK1, DEFTANK2, and DEFTANK302 models. As a direct OEM replacement sourced through Multiquip's authorized parts network, the part meets the exact specifications of the original unit installed at the factory. This assembly ensures the DEF delivery system operates correctly, maintaining proper fluid transfer and dosing integrity across compatible tank configurations. Verified fitment for DEFTANK1, DEFTANK2, and DEFTANK302 makes this the correct part to specify when servicing these systems.

Key Features

• Genuine OEM Fluid Transfer Precision — Built to exact flow-rate and pressure specifications required for accurate DEF delivery in MQ Power tank systems.
• Direct-Replacement Assembly — Designed to install directly into the existing DEF tank housing with no modifications to mounting points or fluid connections.
• Confirmed Fitment — Verified for DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank configurations.
• Maintains DEF System Integrity — A functioning pump assembly ensures consistent DEF fluid movement; a failed pump can interrupt dosing and trigger emissions-related fault codes on connected equipment.
• Emissions System Compliance — Correct DEF pump operation is essential for Tier 4 diesel emissions compliance; using an OEM-spec assembly supports proper SCR system function and helps avoid regulatory issues on the jobsite.

The Remote DEF System Pump Assembly is responsible for drawing diesel exhaust fluid from the storage tank and delivering it under pressure to the dosing system on Tier 4-compliant diesel equipment. Without a properly functioning pump, DEF flow can be interrupted, causing the selective catalytic reduction system to underperform or shut down entirely — which can result in engine derate or fault codes. Replacing a worn or failed pump assembly with the correct OEM part restores full fluid delivery capacity and keeps the emissions control system operating as intended.
