Dual Fueler Install Kit no pump GM 2004.5-2005 LLY

This kit allows the engine computer to automatically recognize and utilize two fuel pumps, delivering the precise amount of fuel requested. The PPE belt-driven Bosch CP3 fuel pump kit works with the stock fuel system and is controlled by a microprocessor module. It reduces the drive load on the stock CP3 pump, increasing reliability. Both pumps work together, each delivering half the total fuel volume. If one pump fails, the electronic controller automatically switches all fuel delivery responsibilities to the remaining operational pump. This kit increases fuel volume as needed to maintain ECU-requested fuel pressure and will not produce more fuel pressure than requested. For racing applications, it provides fuel flow to maintain fuel pressure to 26,000+ psi, essential for highly modified race engines seeking high horsepower.
