What's wrong?
In NHTSA campaign 18V657, the problem is in the fuel pump cooling circuit on affected 2017-2019 Peterbilt trucks with Cummins ISX15 or X15 diesel engines. That circuit helps control fuel temperature around the pump, and the low-pressure nylon fuel line carries fuel after it leaves the pump.
The screen in the cooling circuit can collect excessive debris during extended motoring, such as a long downhill grade. When the screen clogs, fuel leaving the pump runs hotter than designed. That heat weakens the nylon low-pressure fuel line until the line bursts.
There is no warning sign before failure. The filing says the difference is in the fuel-line design: recalled engines used nylon fuel lines, while non-recalled engines used steel fuel lines or nylon lines with added filter screens.
