Useful Information

Description and Purpose:

This Genuine International / Navistar DEF Tank QLS Head comes new under Part number: 4087159C91 and manages sensing, filtration, and suction inside compact 5-gallon DEF tanks. It uses a Deutsch DT4 plug for digital canbus communication, a 40µ in-tank filter, SAE J2044 3/8 suction and 5/16 return fittings, plus heated 5/8 coolant ports that keep fluid thawed.

Why Replacement is Important:

When filtration clogs or sensors send false readings, the SCR system reacts poorly, leading to derate warnings and downtime.

Impact on Vehicle Performance:

A clean, correctly monitored DEF supply keeps emissions stable and prevents unnecessary loss of power.

Manufacturer Information: 

International® provides parts designed to deliver reliable functionality across a wide range of fleet operations.

Navistar® applies strict production standards to deliver durable parts that meet professional trucking demands.
