Fleece PowerFlo In-Tank Lift Pump (FPE-34562) – 2011-2024 Ram 6.7L Cummins

Upgrade your fuel system the smart way. The Fleece Performance PowerFlo Lift Pump (FPE-34562) is a true drop-in, OEM-style in-tank lift pump designed specifically for 2011–2024 Ram 2500/3500 trucks with the 6.7L Cummins. It delivers the flow and reliability needed for stock trucks, tuned daily drivers, and high-horsepower builds (including dual CP3 setups) while eliminating the common headaches of traditional frame-mounted lift pumps.

Why the PowerFlo Stands Out

Unlike noisy external pumps that require cutting into your tank or running new fuel lines, the PowerFlo installs in the factory location using your existing connections. It retains the factory water-in-fuel (WIF) sensor, fuel heater, and fuel lines for a clean, factory-like appearance and function. The integrated active fill bucket technology solves the frustrating ¼-tank fuel starvation issues that plague many modified trucks — no sump or draw straw required.

Inside the module are two OEM-quality gerotor pumps that have been tested for over 12,000 hours. Together they flow 170 GPH @ 15 PSI and support up to 800+ RWHP. A regulated return design prevents over-pressurization, and the in-tank mounting keeps operation virtually silent.

For builders who want to run custom fuel lines or aftermarket filters, the pump outlet and return are threaded to accept -8 O-ring fittings (¾"-16 thread), giving you full aftermarket flexibility without sacrificing the easy in-tank installation.
