Fleece Performance 05-09 Dodge PowerFlo Lift Pump Assembly

Ram 2500 and 3500 owners with a 2005-2009 Cummins usually come looking for a lift pump after a hard start, a stumble under load or a gauge that quit. Starting in 2005, Dodge moved the lift pump off the engine and into the tank, so a tired pump means pulling the sending unit. The Fleece Performance FPE-34560 PowerFlo is a complete in-tank replacement for that assembly. It covers both the late 5.9L trucks and the first 6.7L trucks, and it replaces Mopar RL143160AB and its superseded numbers.

What the in-tank lift pump does on a 2005-2009 Cummins

The lift pump has one job: keep the CP3 high pressure pump full of clean, bubble-free fuel at positive pressure. The CP3 makes rail pressure, but it relies on the lift pump to feed it, and it is lubricated by that same fuel. Low feed pressure shows up first as hard starts and power loss, and over time as CP3 and injector wear. The PowerFlo replaces the single factory pump with two gerotor sections inside the same module. Fleece rates it for up to 800 HP, including dual CP3 setups, and lists 18-20 psi at idle. It keeps the factory water-in-fuel sensor, fuel heater and fuel lines, so the rest of the system stays stock.

Symptoms of a failing lift pump

• Long crank or no start after sitting, especially with a warm engine
• Loss of power or surging while towing or climbing a grade
• Low or falling feed pressure on a gauge at the filter housing
• Stumble or cut-out when the tank drops near a quarter
• Fuel gauge that reads wrong or sticks, since the sender is part of the module
• Rail pressure that cannot keep up with what the ECM asks for under load

How to confirm before you buy

Put a gauge on the test port at the fuel filter housing and check pressure at idle and under load. Change the filter and drain the water separator before you condemn the pump, since a plugged filter reads the same way. If pressure is still low with a new filter, the pump is the likely cause. A truck that bogs or will not shift right under load may have a transmission problem instead. Our 48RE Cummins transmission problems guide covers the 2005-2007 5.9L trucks, and the 68RFE Ram 2500 common problems guide covers the 6.7L trucks.

Fitment

Fleece lists this pump for these pickups:

• 2005, 2006 and 2007 Dodge Ram 2500/3500 with the 5.9L 24V Cummins
• 2007.5, 2008 and 2009 Dodge Ram 2500/3500 with the 6.7L 24V Cummins

It replaces Mopar RL143160AB, 5143160AA, 5143160AB, 68002062AB and 68003465AA. It is not for cab and chassis trucks. 2010 trucks take a different pump, FPE-34561, and 2004 trucks with a dealer-retrofitted in-tank pump need FPE-34755 because their tank uses the plastic locking ring. Compare the number on your sending unit, or send us your year, VIN and cab and bed configuration. More parts for these trucks are on our 48RE parts page and our 68RFE parts page.

Install notes

• Drop the tank or lift the bed to reach the sending unit, and run the fuel level low first.
• Install the new locking ring seal and seat the module straight so the bucket sits on the tank floor.
• Change the fuel filter at the same time and prime the system before the first start.
• The outlet and return accept a -8 O-ring fitting (3/4-16 thread) if you run your own lines or filters later.
• Fleece validates the PowerFlo for up to B20 biodiesel and has fitment data for Titan and S&B tanks.
• If low feed pressure already hurt the CP3, look at the Fleece CP3K for the 5.9L or the Fleece CP3K for the 6.7L.

Will this pump fit my 2008 Ram 3500 with the 6.7 Cummins?

Yes, if it is a pickup. Fleece lists FPE-34560 for 2005-2009 Ram 2500/3500 with the 5.9L or 6.7L 24V Cummins. It is not for cab and chassis trucks.

I have a 2010 Ram. Is this the same pump?

No. 2010 trucks use FPE-34561, which replaces Mopar 68084965AB. 2011-2024 trucks use FPE-34562.

What Mopar part numbers does it replace?

Fleece cross-references it to RL143160AB, 5143160AA, 5143160AB, 68002062AB and 68003465AA.

What fuel pressure should I see after install?

Fleece lists 18-20 psi at idle. Check it at the fuel filter housing test port with a new filter installed.

Do I lose the factory fuel heater or water sensor?

No. The PowerFlo keeps the factory water-in-fuel sensor, fuel heater and fuel lines.

Should I replace anything else with it?

Install a new fuel filter and prime the system. If the truck ran low on feed pressure for a long time, have the CP3 and injectors checked too.
