Shop with Blessed Performance for the Exergy Performance 550 Alpha Stroker CP3 Pump for your 2001-2004 GM 6.6L LB7 Duramax diesel. The first of an industry leading series of pumps set to take the CP3 pump platform to the next level! Based on Exergy Performance's legendary 14mm Stroker pumps, the 550 Alpha CP3 carries the output trajectory 1000 RPM farther than previous and competing CP3 Stroker pumps, peaking at an output of 550 liters per hour. This makes it the perfect pump for high RPM race applications that spin beyond 4500 RPM.
Note: 550 Alpha pumps WILL REQUIRE a different supply line. The original supply port is plugged. This plug should never be removed. The fuel supply is fed directly into the billet gear pump housing at the port labeled "Inlet". The Duramax 550 Alpha pumps are an LBZ based pump with a stock LBZ fuel pressure regulator for optimum rail pressure control without impeding max pump performance. Custom tuning and supporting modifications will be required. Primary fuel supply requirement for max pump performance: 200 GPH @ 8-10 psi per Pump.
