NHTSA campaign 18V412000
Hazard
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.
Consequence
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.
Remedy
Navistar will notify owners, and dealers will replace the straight fitting on the air compressor discharge line and the discharge line with a 45-degree fitting and a redesigned discharge line, free of charge. The recall began on July 20, 2018. Owners may contact Navistar customer service at 1-800-448-7825. Navistar's number for this recall is 18511.
