What's wrong?
The affected 2018-2019 International Hx and Lt trucks use an air compressor as part of the air brake supply system. Its discharge line carries hot compressed air away from the compressor, while the fuel filter inlet and outlet lines move diesel fuel into and out of the filter. Those lines need clearance from heat and rubbing points.
On these trucks, the Wabco 37.4 air compressor discharge line sits too close to the fuel filter fuel lines. The design did not account for the fuel line variations used with the Cummins ISX engine, so the hot discharge line can contact the inlet or outlet line. That contact exposes the fuel line to heat damage instead of leaving the lines separated.
There is no warning sign before failure. International's repair uses a 45-degree elbow fitting and a redesigned discharge line to move the hot air line away from the fuel filter lines.

What should I do?
- Check your VIN to confirm your 2018-2019 International Hx or Lt is included in this recall.
- Contact a franchised International dealer to schedule the free 45-degree fitting and redesigned discharge-line replacement that moves compressor heat away from the fuel lines.
- Bring the recall notice if International mailed one. If not, reference recall number 18V412 when you call.
- Watch for fuel smell or visible fuel leakage until the repair is complete.
- Keep the truck out of service if you smell fuel or see a fuel leak, and ask the dealer how to move it safely.
What happens at the repair
At the dealer, an International technician replaces the straight fitting on the air compressor discharge line and installs a 45 degree fitting with a redesigned discharge line. Parts and labor are free under the recall. The manufacturer's standard reimbursement plan applies to repairs paid before owner notification. If you already paid for a related discharge line or fitting repair, bring documentation and ask the service desk to follow the reimbursement instructions included with the customer notice.
