Useful Information

Description and Purpose:

New Diesel Exhaust Fluid Pump by Detroit Diesel. Part number: RA0001407278. This genuine pump is designed to work with SCR systems by providing steady DEF flow, installed in front inside positions on Freightliner Cascadia, Columbia, M2, and Western Star trucks. It fits Detroit DD13 and DD15 engines, helping reduce NOx emissions and ensuring emission system reliability. Cross Reference Part Number: RA0001407278, DDE RA0001407278, DDE EA0001407278.

Why Replacement is Important:

When the DEF pump fails, it interrupts proper fluid delivery, causing SCR issues and engine derate. Replacing it on time keeps emission systems compliant, prevents power loss, and avoids costly repairs.

Impact on Vehicle Performance:

A working DEF pump supports emission controls and protects engine power and fuel efficiency. It reduces pollutants and keeps your truck reliable and ready for the road.
