The main reason behind this pump's inability to support the fuel demands for your Cummins engine is the fact that first, it's a smaller weak motor that is located near the engine. As with all diesel lift pumps, motors are designed to push fuel and when required to suck fuel over a long distance the added strain will overheat the motors, leading to a drop in fuel pressure. Low fuel pressures can cause a decrease in throttle response, fuel economy, horsepower numbers and even cause damage to your VP44 injection pump. Cummins Direct Replace Pump Features.
