FAQ
Will this pump bolt right in on my LB7/LLY?Physically, yes. Because it’s LBZ-based hardware, LB7/LLY (’01–’05) trucks typically require custom tuning for proper idle/run quality. We recommend coordinating with your tuner.
How much does it flow?Displacement is approximately 1,325 mm³/rev (10mm). Pump output depends on rpm and system health; S&S publishes comparative curves and includes an individual test sheet with each unit.
Do I need a lift pump?Strongly recommended. A quality lift pump (AirDog or FASS) helps maintain inlet supply, reduces cavitation, and improves injector longevity.
Warranty?S&S CP3s are commonly sold with a 2-year warranty through authorized dealers.
