PowerFlo® Lift Pump for 2011-2016 LML DuramaxThe PowerFlo* lift pump, the latest OEM replacement performance lift pump from Fleece Performance, is the only in tank lift pump capable of supporting up to 800 hp!

The PowerFlo* lift pump, the latest OEM replacement performance lift pump from Fleece Performance, is the only in-tank lift pump capable of supporting up to 800 hp! Unlike the LML, which relies on vacuum from the CP4 to draw fuel from the tank, putting extra stress on the injection pump and potentially leading to premature failure, the PowerFlo lift pump provides positive fuel pressure to the CP4, reducing strain on the injection pump and supporting up to 800 hp.

**FEATURES:**

- **Direct OEM In-Tank Replacement:** The PowerFlo lift pump retains the factory fuel lines and installs in less than half the time of other high-flow lift pumps.

- **OEM Quality - Dual Gerotor:** Two is always better than one, and the PowerFlo delivers with two OEM-quality gerotor pumps, increasing flow capacity and reliability compared to the factory pump. Capable of supporting up to 800 hp, including dual CP3 pump configurations.

- **Seamless Integration:** The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the ¼ tank issues typically encountered when seeking a higher-flow lift pump to meet your engine’s needs.

- **Aftermarket Capable:** Want the benefits of an in-tank pump but need to run your own fuel lines or aftermarket filters? The pump outlet and return are threaded to accept a -8 O-ring fitting (3/4”-16 thread).

FPE-34564 is a long bed (8’) fuel pump with two versions: 13578389 and 13578388.

**Application Notes:**

We recommend using our Auxiliary Heated Fuel Filter Kit, P/N FPE-DMAX-HFFBA-1116, in conjunction with our PowerFlo Lift Pump. This filter kit replaces the factory fuel filter housing with a new filter base, an integral high-flow fuel heater, a Water-In-Fuel (WIF) sensor, and a Donaldson spin-on canister-style filter. The updated fuel filter base mounts in the factory location, making it a direct factory replacement. It also provides peace of mind for tackling cold days with a high-flow fuel heater.

**PowerFlo Operating Pressure:** 10-13 psi at idle

**Use:**

- Single fuel tank configurations only

- Pickup-style trucks only (cab and chassis: verify pump P/N to the cross-reference table)

- Titan Fuel Tanks (reference our Fitment Data)

- This pump will not fit S&B fuel tanks.

**Validation:**

- PowerFlo lift pumps are validated for use with up to 20% biodiesel.
