Duramax LML In-Tank Lift Pump Upgrade (Fleece PowerFlo, 2011-2016)

aggregated Aftermarket MPNFleece Performance FPE-LML-PFL-LB / FPE-LML-PFL-SB

Fleece PowerFlo in-tank lift pump assembly, OEM-replacement performance unit (up to 800 hp support per the manufacturer). Two catalog SKUs split by bed: long-bed and short-bed tanks - order the SKU matching the truck bed. Purpose: The LML shipped without an external lift pump; an in-tank upgrade feeds the CP4.2 and simplifies future filter service (see the failure-mode record).
