The AirDog A4SPBC191 FP-150-4G Air/Fuel Separation System from GAP is the perfect upgrade for the fuel system on your 2015-2016 GM 6.6L Duramax LML (Moderate To Extreme).
The AirDog functions by drawing fuel from the fuel tank which contains entrained air/vapor, particle contaminants, and unidentified amounts of moisture. When the fuel passes through the water separator, water and large particle impurities are taken out of it. The fuel then reaches the fuel pump with the remaining entrained pollutants, air/vapor, and water. While the fuel passes through the fuel filter under positive pressure, the leftover particle pollutants are retained. The entrained air and vapor are separated and added back to the tank. The right pressures are then used to supply the clean fuel to your engine. Each kit includes all the plumbing, hardware, wiring, mounting brackets, and other installation-related parts needed.
If you update the components and performance of your diesel engine, it needs better fuel flow. Higher fuel flows cause more agitation in the fuel tank and vacuum at the fuel pump. This decreases the performance of the engine by allowing more air and moisture to enter the fuel system. Air and vapor can also cause galling, pitting, and tip erosion in injector barrel/plunger assemblies. The AirDog removes air from the fuel to prevent long-term damage to your injectors and improper operation of your engine. The AirDog also provides the fuel pressures and flows required for your diesel engine to run as efficiently as possible.
This system was created by AirDog to remove water, pollutants, vapor, and entrained air from diesel fuel. This lift pump and filter system is necessary to provide a steady flow of clean fuel to your engine.
The 4G motor, which AirDog has been utilizing for years with great success, is included in this AirDog system, along with their customary non-adjustable/high flow return base. AirDog is able to offer a reasonably priced system with a tried-and-true and reliable motor design by maintaining this basic architecture.

Keep my dogs occupied
Color: Grey
Great for the dogs. Challenging and makes them work at it but not so hard they can’t eventually figure it out.

Too easy for my Lab
Color: Blue
My lab figured this out in 30 seconds. I was hoping it would be a bit more challenging for him. Thankfully, it is challenging enough for my bunny!
