Minimum maintenance has been designed into every QSL. A two-stage dual fuel filter provides a balanced level of particle separation to maximize fuel filter life and protect the vital fuel system components. An integrated water pump, lube pump and cooler housings and coolant bypass eliminate possible leak points. QSL engines are designed to run up to 500 hours between scheduled fuel and oil filter changes.
