The Fleece Performance PowerFlo In-Tank Lift Pump (FPE-34563) is a direct OEM replacement performance lift pump designed for 2011-2016 LML Duramax engines in Chevrolet/GMC Silverado/Sierra 2500HD/3500HD short bed (6.5') pickup trucks. It provides positive fuel pressure to the CP4 injection pump, reducing strain and preventing premature failure. This pump is capable of supporting up to 800 hp, including dual CP3 pump configurations. Key features include dual Gerotor pumps for increased flow and reliability. It operates at a pressure of 10-13 psi at idle and integrates seamlessly with an active fill bucket, eliminating the need for tank sumps or draw straws. The pump outlet and return are threaded to accept a -8 O-ring fitting (3/4"-16 thread) for custom fuel lines or aftermarket filters, making it aftermarket capable. It is important to note that this lift pump will not fit S&B fuel tanks. For compatibility with Titan Fuel Tanks, reference Fleece Performance Fitment Data.
