Useful Information

Description and Purpose:

This Genuine Mopar Diesel Exhaust Fluid (DEF) Supply Pump Module, carried under Part number: 7660448AB, is supplied new. It precisely meters DEF to the SCR system in Ram 2500–5500 series vehicles from 2017–2019, supporting engines from 6.4L V8 Gas to 6.7L L6 Diesel. Reliable DEF flow helps maintain emissions control and ensures steady engine operation.

Why Replacement is Important:

A failing pump can reduce DEF flow, causing engine warnings or temporary power reduction.

Impact on Vehicle Performance:

Maintaining consistent DEF delivery keeps emissions systems active, engine performance stable, and prevents costly downtime.

Manufacturer Information:
