Recall 18V588 affects 26,288 2017-2019 International diesel trucks for burst fuel lines and stalling. Repair is free at any franchised International dealer.
International is recalling 26,288 2017-2019 Prostar, Lonestar, Paystar, Hx, 9900I, and Lt trucks because a restricted fuel pump cooling circuit screen can make the fuel line burst during certain driving conditions, including long downhill grades. If the line bursts, fuel can leak onto the road and the engine can stall without warning, raising crash risk; International dealers will complete the repair free of charge.

What's wrong?
The fuel line in these 2017-2019 International Prostar, Lonestar, Paystar, Hx, 9900I, and Lt trucks carries diesel from the fuel pump gear pump outlet to the engine-mounted fuel filter inlet. A fuel pump cooling circuit screen is part of that system. Its job is to keep fuel moving through the pump area so heat does not build up in the low-pressure line.
The affected trucks use Cummins ISX15 or X15 engines with a nylon low-pressure fuel line and a banjo bolt that has a single integrated screen filter. If that screen becomes restricted during extended motoring, such as a long downhill grade, fuel leaving the pump gets hot enough to weaken the nylon line. The line then bursts instead of staying sealed under normal fuel flow.
The listed warning comes after the line fails. The driver can smell diesel fuel or see diesel fuel on the road after the fuel line bursts.
