Fleece Performance 11-24 Dodge Ram 4500/5500 Cab & Chassis PowerFlo Lift Pump (22 Gal)
This is the Fleece PowerFlo lift pump for the 22-gallon midship fuel tank on 2011-2024 Ram 4500 and 5500 cab and chassis trucks with the 6.7L Cummins, part number FPE-PF-CUMM-1124-CCMS. Fleet and upfit owners usually go looking for it after a factory in-tank pump fails: the truck cranks and will not start, dies under load with a box or a trailer, or sets low fuel pressure codes. It goes in where the factory module sits, so you replace the failed pump and get a stronger one in the same job.
On the 6.7L Cummins the lift pump in the tank feeds low-pressure fuel to the filter and on to the CP3, which then builds rail pressure for the injectors. When that feed pressure drops, the CP3 runs short and the engine loses power or will not start. The PowerFlo replaces the factory pump with two OEM-quality gerotor pumps sitting in an active fill bucket that keeps its own pickup flooded, so it does not need a sump or draw straw and avoids the low-tank fuel starvation that comes with feeding a high-flow pump through a stock pickup. Fleece lists 18-20 psi at idle and rates the pump to support up to 800 hp.
It keeps the factory water-in-fuel sensor, fuel heaters and fuel lines. If you later want your own lines or remote filtration, the outlet and return are threaded for -8 O-ring fittings (3/4-16).
Put a fuel pressure gauge on the supply side ahead of the CP3 and compare it to the 18-20 psi idle figure, then check again under load. Check the pump fuse and relay and the connector at the tank before you condemn the pump. A plugged filter can mimic a weak pump, so change it first. These trucks also work their transmissions hard, so if the truck is in limp mode, find out whether the fault is fuel or transmission first. Our Aisin heavy-duty six-speed guide covers the chassis cab Aisin, and the 68RFE vs Aisin comparison explains which unit your truck has.
Fleece lists this kit for 2011 through 2024 Ram 4500 and 5500 cab and chassis trucks with the 6.7L 24-valve Cummins. It replaces factory part number 68064422AB in the midship 22-gallon tank, and its interchange list also shows 04560227AC. It is for cab and chassis trucks only and will not fit a pickup.
Upfits vary a lot, and some trucks carry an over-axle tank with a midship transfer tank. Match the number on the module in your midship tank, or send us the year and VIN before you order. Transmission parts for these trucks are on our Aisin parts page.
Fleece estimates about 3 hours and notes that cab and chassis configurations vary, so some trucks need extra steps. Bring the tank down to a quarter full or less. Support the midship tank on a jack, remove the two 16 mm strap bolts, lower it a few inches, and disconnect the feed, return, transfer line and harness. Clean the top of the tank, knock the lock ring out with a hammer and punch, and throw away the old flange O-ring.
Clip the included float onto the resistor card without pinching it, fit the new O-ring, set the unit in the same way the factory unit faced, and drive the lock ring home. Midship trucks with a transfer line use the included 5/16 in quick-connect fitting in place of the hex plug. With everything connected, cycle the key on for five to six seconds two to three times to prime before starting, then check for leaks. Fit a new fuel filter at the same time, and if the truck is due, an Aisin service kit is easy to do while it is on the lift.

It depends on the tank. The 22-gallon midship tank takes FPE-PF-CUMM-1124-CCMS (this kit). The 52-gallon over-axle tank takes FPE-PF-CUMM-1124-CCOA. Check the module part number or send us your VIN.
Fleece lists it as replacing Mopar 68064422AB in the midship 22-gallon tank, with 04560227AC also on its interchange list.
No. This kit is for cab and chassis trucks only. 2011-2024 Ram 2500 and 3500 pickups use FPE-34562.
Fleece lists 18-20 psi at idle. Check supply pressure ahead of the CP3 with a gauge after the install.
Yes. The PowerFlo keeps the factory water-in-fuel sensor, fuel heaters and fuel lines, so nothing on the dash changes.
Turn the key on for five to six seconds and off again, two to three more times, then start the truck and check for leaks, per the Fleece instructions.
