The Cummins 6BT 5.9L is one of the most iconic and widely deployed diesel engines in history — a 5.9L inline-6 mechanical diesel powering trucks, construction equipment, agricultural machinery, and marine vessels worldwide. Known for its legendary durability and simplicity, the 6BT uses a mechanical rotary injection pump (6A106P) for precise fuel delivery. When the injection pump fails, you'll experience hard starts, rough running, power loss, excessive black smoke, or a complete no-start condition. This brand-new aftermarket fuel injection pump is a direct replacement for the Cummins 6BT 5.9L 160HP engine with two cross-reference part numbers: 3913902 and 4996844.
