The LB7 PowerFlo lift pump, the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance, offers a seamless solution for your diesel engine’s fuel needs.

 

**Key Features:**

 

- **Direct OEM In-Tank Replacement:** The PowerFlo Lift Pump retains the factory fuel lines, ensuring a hassle-free installation process. It can be installed in less than half the time compared to other high-flow lift pumps.

- **OEM Quality:** New sending unit electronics and a fuel level float restore your fuel gauge’s accuracy.

- **Seamless Integration:** The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the common ¼ tank issues associated with higher-flow lift pumps.

- **Aftermarket Capable:** If you prefer to use 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).
