Product Description
Upgrade the heart of your 6.7L Cummins fuel system with the FLEECE FPE-34562 11-24 DODGE 2500/3500 CUMMINS POWERFLO IN-TANK LIFT PUMP ASSEMBLY. This direct OEM in-tank replacement solves noisy frame-mounted lift pump issues, quarter-tank fuel starvation, and flow limitations – all while supporting 800+ RWHP with quiet, factory-style operation.
The PowerFlo is the only in-tank lift pump of its kind for late-model Ram Cummins. With dual OEM-quality gerotor pumps flowing 170 GPH @ 15 PSI, integrated bucket design, and full use of the factory wiring, fuel lines, fuel heater, and water-in-fuel sensor, it’s the cleanest way to feed stock trucks, big-tune tow rigs, and even dual-CP3 setups.

FAQ – FLEECE FPE-34562 POWERFLO IN-TANK LIFT PUMP
How much power will the FPE-34562 PowerFlo support?The dual gerotor design flows roughly 170 GPH @ 15 PSI and is rated to support 800+ rear-wheel horsepower when paired with appropriate high-pressure fuel components (CP3/CP4 or dual CP3 setups), injectors, and tuning.
Is this a direct drop-in replacement for my factory sending unit?
Yes. The PowerFlo FPE-34562 is a direct in-tank replacement for the OE fuel module on 2011–2024 Ram 2500/3500 6.7L Cummins pickups (excluding Cab & Chassis and 50-gallon tank trucks). It plugs into the factory wiring, uses the stock fuel lines, and drops into the tank like an OE assembly.
Does this pump fix the “¼ tank” fuel starvation issue?
Yes. The built-in active fill bucket design eliminates the common quarter-tank issues seen with many frame-mounted lift pumps. It keeps the bucket full and the pump supplied with fuel even at lower indicated tank levels, so you can safely use more of your tank’s capacity.
Will it work with Titan or other aftermarket fuel tanks?
The PowerFlo is designed primarily for the OEM tank. Some aftermarket tank manufacturers (such as Titan) specifically support the FPE-34562 module – always verify with the tank maker’s fitment data before installing. When in doubt, check their application notes or contact CPP Diesel for guidance.
Is this pump legal for street use?
Yes, for most on-road applications. The pump is associated with CARB EO D-834-12 for applicable vehicles and configurations. Always confirm current emissions rules and EO coverage for your specific year, configuration, and location before installing any emissions-related components.
Can I run biodiesel with the PowerFlo?
The FPE-34562 PowerFlo is validated for use with up to B20 (20% biodiesel). For higher biodiesel blends, consult Fleece Performance or a qualified diesel shop regarding seal compatibility and service intervals.
