This SureFlo performance sending unit fits 2011-2016 GM Silverado and Sierra 2500HD/3500HD long bed with the 6.6L LML Duramax and lets an externally mounted aftermarket lift pump draw from the tank without a sump or draw straw.

Key Features

  • OEM style fitment that requires no cutting or drilling of the fuel tank
  • Factory style quick connect fittings adapt the stock fuel lines at the tank
  • Draws fuel from and returns fuel to the bucket assembly at the base of the unit, so the pump pulls fuel instead of air
  • Eliminates the quarter tank issues associated with a draw straw
  • One way check valves in the bucket let fuel flow in easily at low fuel levels
  • Also serves as a replacement fuel level sender
