LML Duramax AirDog Lift Pump Package | Pump + Sump + FFD | 2011-2014 Chevy/GMC Duramax

The AirDog® Fuel Preporator®, with the capability to provide fuel at flows and pressures beyond the maximum requirements of the engine, receives fuel under vacuum from AirDog® - The Original Fuel/Air Separation Systemthe fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. The fuel passes through the water separator which removes the water and large particulate contaminates that could damage or jam the gerator fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump.

The fuel, now under positive pressure flow, enters the filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented Fuel Preporator® the separated air/vapor is discharged from the filter through the Primary Air/Vapor Discharge Port and into the return to tank passage after the regulator. The fuel passing through the filter media (free of contaminates & power robbing air/vapor and at pressures and flows to meet the needs of the engine exits the fuel filter through two passageways. The fuel for the engine, passes into the fuel pickup tube and out to the engine).

The excess fuel not needed by the engine is released through the pressure regulator to combine with the air/vapor and foam as it returns to the fuel tank. The regulator controls the fuel pressure to the engine.

Package Options

Once you’ve installed an aftermarket Fuel Filtration System, the use of the factory fuel filter is no longer required and can be removed. Because your Duramax factory fuel filter is located after our filtration system you will still need to replace the factory filter every 5,000-8,000 miles. This filter delete kit will replace your now useless fuel filter with a spin on canister that will allow fuel to flow freely into the engine, saving you even more money. This spin on Fuel Filter Delete Kit is a perfect addition to your AirDog fuel pump and comes with all required hardware for a professional installation.
