Useful Information

Description and Purpose:

Diesel Exhaust Fluid Pump by Detroit Diesel, Part Number: A0011400678, condition: new. This genuine DEF pump fits front internal positions on Freightliner Cascadia, Columbia, M2, and Western Star trucks. It ensures steady DEF flow to reduce nitrogen oxide emissions for Detroit DD13 and DD15 engines. Cross Reference Part Number: EA0011400678, DDE EA0011400678.

Why Replacement is Important:

Over time, DEF pumps can clog, leak, or lose pressure. This leads to reduced SCR performance and emission faults. Replacing the unit restores proper DEF dosing, maintains compliance with emission laws, and avoids unexpected system failures or derates during operation.

Impact on Vehicle Performance:

A healthy DEF pump ensures proper emission control, allowing the engine to run smoothly under load. It prevents engine derate, keeps diagnostic lights off, and helps maintain optimal torque, fuel economy, and vehicle uptime in real-world driving.

Manufacturer Information:

Detroit Diesel® is a leading OEM brand trusted for delivering advanced diesel engine solutions. Their parts are engineered to strict quality standards, offering reliable performance and seamless integration with modern emission systems for maximum operational uptime.
