Bosch P7100 Fuel Injection Pump — 1994–1998 Dodge Ram Cummins 5.9L 12-Valve

The Bosch P7100 is the most celebrated injection pump in the diesel truck world — and for good reason. Fitted to the 1994–1998 Dodge Ram with the Cummins 5.9L 12-valve engine, the P7100 is renowned for its mechanical simplicity, bulletproof reliability, and legendary tunability. Whether you're restoring a high-mileage 2nd Gen Ram to factory performance or building a high-output diesel, this brand-new aftermarket P7100 pump delivers OEM-spec fuel pressure and injection timing right out of the box.

Why Replace Your P7100?

A worn P7100 causes hard starts, loss of power, excessive black smoke, and poor fuel economy. Unlike electronic injection systems, the P7100 is a fully mechanical pump — which means it's repairable, tunable, and when replaced with a quality unit, it's good for hundreds of thousands of miles. Don't let a worn pump hold back your 12-valve.
