Engineered specifically for 2003 through 2007 Dodge Ram 2500 and 3500 trucks powered by the 5.9L 24-valve common-rail Cummins turbo diesel engine, the Fleece Performance Dual CP3 Pump Installation Kit (FPE-DPK-59-0307) provides the comprehensive hardware foundation required to build a high-displacement dual-pump fuel system. When tuning competition engines beyond 700 to 800+ rear-wheel horsepower, high injector duration empties the common rail rapidly, resulting in lost rail pressure, delayed fuel injection, excessive smoke, and elevated exhaust gas temperatures (EGTs).

Fleece solves common-rail fuel starvation with a low-mount auxiliary bracket design that mounts the secondary CP3 pump securely to the front gear housing. Unlike competitor brackets that block cylinder head access, Fleece’s unique mounting architecture does not require secondary pump removal when removing or servicing the engine cylinder head. Furthermore, the kit includes Fleece’s exclusive pump-to-pump high-pressure line and non-return check valve, which directly connects the secondary pump to the primary pump. This eliminates the need to remove or remotely relocate the factory fuel rail pressure sensor. Sold complete without a high-pressure pump, this hardware package includes the electronic pump controller, idler assembly, belt, and mounting hardware to support up to 1,200+ horsepower.

Key Features & Benefits

• Supports 1,200+ Rear-Wheel Horsepower: Doubles high-pressure pumping capacity to maintain commanded fuel rail pressure on large-injector competition builds.
• Exclusive Pump-to-Pump High-Pressure Line: Plumbs the secondary CP3 directly into the primary CP3 feed circuit, avoiding clumsy rail sensor relocation blocks.
• Zero Pump Removal for Head Gasket Work: Front-cover mounting geometry allows full cylinder head removal and installation without dismounting the secondary CP3 pump.
• Electronic Dual Pump Controller Included: Comes complete with the electronic module to synchronize metering signals across both Fuel Control Actuators (FCAs).
• Complete Auxiliary Drive Assembly: Includes the auxiliary idler pulley, custom spacer, extended high-load serpentine belt, and fan shroud bracket.
• User-Supplied Pump Architecture: Sold without the secondary pump, allowing builders to choose a stock replacement or modified stroker CP3 pump.
• Zero Core Charge: Sold outright as brand-new engineered hardware with no core deposit or core return required.

Vehicle Fitment & Technical Installation Notes

• 2003–2007 Dodge Ram 2500 – 5.9L Cummins 24V Common-Rail Diesel
• 2003–2007 Dodge Ram 3500 – 5.9L Cummins 24V Common-Rail Diesel
• Fits Model Years: 2003, 2004, 2004.5, 2005, 2006, 2007
• Intake Horn Clearance Notice: This kit will not clear the factory OEM cast intake horn. An aftermarket intake elbow (such as a Banks Monster Ram or similar low-profile aftermarket intake horn) must be used to provide pump clearance.
• Secondary Pump Specification: The secondary (upper) mounting bracket is engineered specifically around a 2007.5–2018 6.7L Cummins Bosch CP3 pump housing.
• 2003–2004 APPS Note: On early 2003–2004 trucks equipped with the engine-mounted Accelerator Pedal Position Sensor (APPS), the APPS bracket assembly must be relocated to clear the secondary CP3 drive belt path.
• Lift Pump Prerequisite: A high-output electric fuel lift pump rated at 165 to 250+ GPH (such as FASS Titanium or AirDog II-5G) with 1/2" supply plumbing is required to supply sufficient volume to both high-pressure pumps.
