This kit does not require any fuel tank modifications for installation.

The Pureflow AirDog II 5G 165 GPH A7SABC513 Air/Fuel Separation lift pump, or Fuel Preporator, is a must have upgrade for your 2015-2016 6.6L LML Duramax. The fuel system on your LML is the heart of the vehicle’s performance and reliability. This low pressure (preset at 8-10 psi) LML lift pump mounts in front of the fuel tank to the frame jig . The pressure side feeds the CP4 injection pump through the factory feed line on the frame. The suction/fuel supply side connects directly to the factory quick disconnect fittings on the fuel module making the install very straight forward. The Duramax sees the most benefit from adding an AirDog lift pump fuel system.

The II-5G features a fully adjustable (7-55psi) integrated diaphragm pressure regulator. This regulator offers more consistent fuel pressure and allows for higher flow rates at pressure.  It can also be boost compensated to battle any pressure drops under open throttle (boost compensation kits sold seperately).  The AirDog 5G also includes an updated 12 gauge wiring harness with Metri-Pack 280 connectors, which allows for higher current flow without creating excessive heat.

Over the life of your diesel pickup truck there may be unnecessary stress on your fuel system. High mileage and/or additional performance modifications such as a tuner or oversized injectors can weaken your injection pump, or CP4, in a shorter amount of time than with the stock fuel system. This may result in a drop in performance, reliability, and fuel economy.  Installing an AirDog II-5G lift pump will strengthen, protect, and in most cases extend the life of the fuel system and related parts. The supplied fuel filter (FF100-2) and water separator (WS100) filter your fuel down to a 2 micron rating, which surpasses the stock fuel filters capability.  The AirDog 2 5G also helps by eliminating spray pattern disruption from air entering the diesel fuel system. The result is overall increased engine efficiency by keeping the injection timing where it should be thus allowing a more complete burn of the fuel entering the cylinder. (see How It Works)

The AirDog 2 5G DF-165 will solve the infamous P0087 & P1093 low fuel rail pressure codes by supplying your CP4 injection pump with fuel, rather than your injection pump doing most of the work pulling the fuel up from the tank. This positive supply of purified fuel being fed to your injection pump will also add performance, throttle response, and longevity to your vehicle.

The AirDog II 5G 165GPH LML lift pump is recommended for Duramax trucks that have a stock to aggressively upgraded fuel system (meaning stock to larger injectors and injection pump; will also support aggressive tuning). Perfect fit for daily drivers to performance applications reaching up to 800 RWHP.  Backed by a lifetime warranty.

The AirDog II-5G DF-165 for the 15-16 Duramax is engineered with the most proven, quiet and reliable motor technology on the market.  It also retains the “demand flow” capabilties of the previous AirDog II systems.  This means that is has a constant supply of clean, pure fuel available for your injector pump at all times.  Any fuel not used by the engine is simply recycled back to the tank, so it will never “over-fuel” your system.   The II-5G A7SABC513 uses the same better-than-OEM fuel filter (FF100-2) and water separator (WS100) as the previous AirDog II models.  Pureflow AirDog products are manufactured in Shelbyville, Indiana by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.
