What's wrong?
The fuel pump on the 2017-2018 Spartan K3, K4, and Gladiator chassis feeds diesel fuel to the Cummins ISX 15L engine. Its drive gear turns on a drive shaft, which keeps the pump moving fuel at the pressure the engine needs to keep running.
On these chassis, the fuel pump drive gear was assembled incorrectly onto the drive shaft. The gear can slip instead of turning the shaft as designed. When that happens, the pump stops doing its job, fuel delivery drops, and the engine can stall.
The Spartan filing points to Cummins recall 17E-029 for warning details and does not identify a clear owner warning sign in this record. There is no warning sign before failure. A dealer can identify the recalled pump by its serial number, and replacement pumps use different serial numbers from the recalled parts.
