Useful Information

Description and Purpose:

This New, Genuine International 9.5 Gallon DEF Tank QLS Sensor Head, Part Number: 4397723C91, designed for commercial vehicle emission systems. It delivers accurate diesel exhaust fluid level monitoring in heavy-duty environments and fits various Severe Service and Linehaul models. As a critical part of the DEF tank assembly, it ensures reliable data transmission to maintain proper emission control functions under high-demand operations.
