Fleece Performance PowerFlo In-Tank Lift Pump for 2011-2013 Chevrolet Silverado 3500 HD (6.6L) - Long Bed
$799.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2011-2013 Chevrolet Silverado 3500 HD (6.6L) pickup trucks with a long bed (8') and single fuel tank configuration.
The Fleece Performance PowerFlo in-tank lift pump (FPE-34564) is a high-performance OEM replacement designed to protect your LML Duramax's fuel system. Factory 2011-2013 LML engines rely on the CP4 injection pump to pull fuel from the tank under vacuum, which increases strain and risks premature pump failure. The PowerFlo provides positive fuel pressure to the CP4, reducing stress and supporting performance builds up to 800 hp, including dual CP3 configurations.
Built for reliability and ease of installation, this lift pump features a dual gerotor design and an active fill bucket that eliminates common 1/4-tank fuel starvation issues without needing tank sumps or draw straws. It installs directly into the factory location, retaining original fuel lines while offering the flexibility to run aftermarket lines via threaded ports.
- Manufacturer Part Number: FPE-34564
- Dual Gerotor Pump: Increases flow capacity and reliability
- Capacity: Supports up to 800 hp
