The ATC J-46375-A Injector Unit Pump Puller Tool is a precision-engineered diesel service tool designed to safely and efficiently remove unit fuel pumps (U-pumps) from Mercedes-Benz Trucks MBE 900 diesel engines. These injector unit pumps are often tightly fitted and may seize due to carbon buildup, heat cycling, or extended service life. Improper removal methods—such as prying, hammering, or using improvised tools—can damage the pump body, cylinder head bore, sealing surfaces, or surrounding components. The ATC J-46375-A provides secure engagement and straight, even extraction force for clean and controlled removal.
Ideal for commercial truck repair shops and fleet maintenance operations, this diesel injector pump removal tool is built for repeated heavy-duty use. It allows technicians to service fuel systems with greater precision, reduced downtime, and improved safety compared to improvised extraction techniques.
