    • WILL THE POWERFLO FIT MY TITAN FUEL TANK?
      • Yes. Check out their fitment table HERE.
      WHAT SIZE INJECTORS DOES THE POWERFLO 750 SUPPORT?
      • Injector size should be based off of desired horsepower goals, truck uses, and tuning capabilities. Commanded main injection duration, or tuning, ultimately determines what size injector a CP3 will support. Their PowerFlo750 will support their 100hp injector at 2600uS with no issue, resulting in over 750RWHP if your turbo will support that. Some people have seen over 800rwhp with shorter durations and larger injectors on FPE 68mm turbos and larger.
      WHAT IS MAIN INJECTION DURATION?
      • Main Injection Duration is the amount of time that the injector is turned on or energized. Measured in micro-seconds (uS) it is sometimes referred to as pulse-width.
      WHAT DOES A CP3 PUMP DO?
      • A common rail fuel system is most easily related to supply & demand. Commanded main injection duration, the demand, while the CP3 is the supply. The bigger the injector and/or longer the commanded duration, the higher the demand. CP3s are limited to what they can supply (Volume) based on displacment & RPM. As demand increases beyond the CP3s ability to supply, then fuel rail pressure starts to drop.
