2004.5-2005 LLY Duramax PPE Dual Fueler Kit W/CP3 Pump PPE -113062000
By simply bolting this kit on, your engine computer will automatically recognize both pumps and continue to deliver the precise amount of fuel your engine computer is requesting. Two is better than one. The single stock CP3 pump runs out of fuel well before peak power is produced. The solution is to install a second belt driven Bosch CP3 pump. The Dual Fueler pump and factory pump work in conjunction, each delivering half of the total fuel volume requested by the engine computer. In the event of one pump failing the electronic controller will automatically switch all fuel delivery responsibilities to the remaining operational pump. This kit will not produce more fuel pressure than the engine ECU requests; it will only increase fuel volume as needed to maintain ECU requested fuel pressure. For racing applications this kit provides fuel flow to maintain fuel pressure to 26,000 psi that is essential for highly modified race engines that are seeking to produce up to 2,000 hp.
– Provides additional horsepower and fuel pressure
– Easy bolt on installation
