The defect
Navistar, Inc. (Navistar) is recalling certain 2018-2019 International HX and LT trucks equipped with a Cummins ISX engine and a Wabco 37.4 air compressor. The air compressor discharge line may contact the fuel filter inlet and outlet lines (fuel lines) and the heat generated from the air compressor discharge line may cause heat damage to the fuel lines.
The risk
Continued heat damage to the fuel lines could cause the fuel lines to rupture, resulting in a fuel leak and increasing the risk of a fire.
