Product Details

Diesel Exhaust Fluid systems rely on accurate pumping and clean fluid handling to protect the SCR system from contamination and dosing issues. Cardone 5D-9000 is engineered for Mercedes-Benz DEF pump service where the original unit has failed, leaked, or lost pressure. This remanufactured unit is designed around the needs of modern diesel emissions systems and supports reliable DEF transfer in vehicles such as the Mercedes-Benz Sprinter 2500, Sprinter 3500, GLE300d, E250, GL350, GLK250, ML250, ML350, and E350. This part cross-references Mercedes-Benz (e.g., 24706894, 68192659AC) for the same application.

What It Helps Address

• DEF pump failure or weak fluid delivery
• Emission system faults related to improper DEF pressure
• Leaks caused by worn seals or damaged pump components
• Noise from a deteriorating factory pump
• Service issues tied to contaminated or poorly handled DEF

Installation Notes and Tips

Verify connector style, port layout, and outlet thread diameter before installation. The pump uses a 3 male connector and includes a 1/4-inch outlet thread diameter, so matching the OE configuration is important for proper fitment. Clean the DEF system components during service and follow the vehicle manufacturer’s procedures to avoid contamination that can affect injectors or catalyst performance.
