What's wrong?
The fuel pump cooling circuit screen on affected 2016-2019 Volvo Vnl trucks with Cummins ISX15 diesel engines is part of the fuel pump plumbing. It sits in the banjo bolt, the hollow fastener that routes fuel through the pump circuit, and it is supposed to keep debris from restricting fuel flow. The low pressure nylon fuel line then carries fuel from the pump outlet to the engine-mounted fuel filter inlet.
The problem starts when that screen becomes restricted during certain driving conditions, including a long downhill grade. Under extended motoring, fuel leaving the fuel pump gear pump gets hot enough to weaken the nylon line between the pump and filter. Once the material strength drops, the line bursts and diesel fuel escapes.
The warning sign listed for this recall comes after the line has burst. The driver can smell diesel fuel or see diesel fuel on the road.
