PPE Dual Fueler Kit For 2002-2004 Duramax LB7 Doesn't Include Second Pump

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 switches 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

The Dual Fueler Kit is also available with second pump.
