Fleece ½″ High-Flow Feed-Line Kit (OEM Filter → CP3) | 2010-2018 Cummins Ram 2500/3500

Fleece ½″ High-Flow Feed-Line Kit (OEM Filter → CP3) • 2010-2018 Ram 2500/3500 6.7 L Cummins

Replace the restrictive factory 3⁄8″ supply hose with Fleece’s ½-inch High-Flow Feed-Line Kit and keep your 6.7 L Cummins CP3 pump fed with up to 40 % more volume at wide-open throttle. Maintaining adequate supply pressure helps the injection system deliver consistent rail pressure, protects pump longevity, and frees horsepower for towing, tuning, or weekend fun.

Why You’ll Want It

• Bigger ½″ ID hose slashes pressure drop between the OEM filter head and CP3 pump.
• Direct-fit quick-disconnect and CP3 fittings-no cutting, flaring, or guessing.
• Supports 600 + rwhp builds or high-duty cycle towing without starving the rail.
• USA-made components assembled by Fleece Performance for OE-grade reliability.

Kit Contents

• ½″ push-lock fuel hose (cut-to-length)
• ½″ quick-disconnect feed fitting (fuel filter outlet)
• High-flow CP3 inlet fitting (pump side)
• Installation guide & clamps
