2011-2016 LML Crew Cab Duramax Fass Fuel System Relocation Mounting Bracket for Chevy Silverado or GMC Sierra 2500 / 3500 trucks. WCFab’s precision laser cut bracket relocates the FASS fuel system to underneath the truck just in front of the fuel tank on the inside of the driver side frame rail moving the lift pump out of the debris path of the rear tires. Provides a stealthy, hidden installation when paired with FASS short style filters and simplifies fuel line routing when using a sump style pickup on the tank.
