Fleece Performance PowerFlo In-Tank Fuel Lift Pump FPE-PF-CUMM-1124-CCMS — 2011–2024 Ram 4500/5500 Cab & Chassis 6.7L Cummins (22-Gallon Midship Tank)

The Fleece Performance PowerFlo In-Tank Lift Pump (FPE-PF-CUMM-1124-CCMS) is the cleanest and most reliable way to upgrade the low-pressure fuel system on your 2011–2024 Ram 4500 or 5500 Cab & Chassis 6.7L Cummins. Designed specifically as a direct replacement for the factory lift pump in the 22-gallon midship tank, the PowerFlo gives your engine the consistent fuel supply it needs for towing, performance upgrades, or demanding work applications — all while keeping your fuel system looking and functioning like stock.

Unlike frame-mounted or sump-style lift pumps that require cutting the tank, running new lines, and losing factory features, the PowerFlo drops straight into the factory location. You keep your factory fuel heater, water-in-fuel (WIF) sensor, and factory fuel lines. Installation typically takes less than half the time of competing systems.

At the heart of the PowerFlo are two OEM-quality gerotor pumps working together. This dual-pump design dramatically increases flow capacity and reliability over the single factory pump, supporting up to 800 horsepower (including dual CP3 setups). The innovative active fill bucket technology ensures the pumps stay submerged even at low fuel levels, completely eliminating the common “1/4 tank starvation” problem found in many aftermarket systems.

For builders who want to run custom fuel lines or aftermarket filtration, the pump outlet and return ports are threaded to accept -8 O-ring fittings (3/4"-16 thread), giving you maximum flexibility.

Key Benefits:

• Supports up to 800 HP fuel delivery
• Retains factory fuel heater, WIF sensor, and fuel lines

Why Choose the PowerFlo for Your Cab & Chassis?

Cab & chassis trucks often see heavy use, long hours, and frequent heavy loads. The factory lift pump can struggle to keep up once you add tuning, larger injectors, or simply demand more consistent fuel delivery. The PowerFlo gives you the fuel supply you need without turning your truck into a custom fuel system project. It’s the smartest upgrade for reliability-focused builds that still want to maintain a clean, factory-like appearance and functionality.
