AirDog LML II-5G 220GPH Air/Fuel Separation System | 2011-2014 GM Duramax LML 6.6L

The AirDog® II-5G Fuel Air Separation System for the 2011-2014 GM Duramax 6.6L diesel introduces an industry-first, integrated diaphragm fuel pressure regulator; allowing for more fuel pressure adjustability, better fuel flow at pressure, and can be boost compensated. Larger porting allows less cavitation and noise and an improved wiring harness allows more current flow without producing more heat.

The AirDog® II-5G System Improves Engine Performance by eliminating spray pattern disruption due to air entering the system. This allows the engine to keep its designed injection timing which allows a more complete burn of the fuel entering the cylinder. This increases overall engine efficiency across the power and torque range!

How AirDog® Works

All Diesel Engines Need a 'State of the Art' Fuel Filtration Delivery System!

The solution is Fuel Preporator® – the only filtration delivery system that separates air from the fuel, as well as water and particulates, and maintains the proper pressure flow to the transfer pump, eliminating cavitation and vapor. Fuel Preporator significantly improves diesel engine performance.

Fuel Preporator's effectiveness has been proven over millions of truck miles. Discover how patented Fuel Preporator technology can deliver for you:
