FAQ
Will this replace my CP3 injection pump?
No. This is a frame-mounted lift pump that supplies clean, regulated fuel to your factory CP3. It does not replace the injection pump.
Do I need a return line with the RP-4G-100?
No. The RP-4G-100 is internally regulated and does not require a return line.
What truck models does R4SBC133 fit?
2001–2010 GM Duramax LB7, LLY, and LBZ (see detailed fitment above).
What if I plan future performance upgrades?
For larger injectors or elevated power levels, consider stepping up to an AirDog II-5G DF-100/DF-165 system (see Cross-Reference links).
