1994-1995 Cummins 5.9L High Power Injection Pump P7100 300hp 5Speed (1051841)Adding springs, valves, plates or making adjustments can increase the power output from a P7100 pump, but, to do so on the vehicle can cause excessive heat, smoke, grief, time and damage. Having a pump that is already completely remanufactured with all the highest quality parts, calibrated on world class equipment and the extra added touches only nearly 50 years of experience can offer will guarantee peak performance and efficiency.
