Provides Optimized Fuel Stream

The fuel system for the 7.3L Powerstroke V8 in your F250 or F350 is good enough to give your truck some pretty good performance under light-duty conditions, but when things get rough or extreme, trapped air and water vapor causes your fuel system to work below its optimal efficiency. To keep your truck's fuel system working at its peak, you'll need to grab the original AirDog Fuel Preporator System and get back lost power and engine efficiency. This powerful air/fuel separator pulls trapped air bubbles and water molecules out of your truck's fuel stream which gives your 7.3L a more pure fuel mix for more power, better fuel economy, and more reliable engine function.

Improves Power And Reliability

When your truck is out doing all those great things that truck's do, your fuel sloshes around in your gas tank. As it sloshes, air bubbles and water vapor become "entrained" with your diesel fuel and brought into your fuel system. These small bubbles may not seem like much, but they cause inefficient fuel injector function and engine combustion which leads to a loss of performance, rough idle, surging, poor gas mileage, and shorter fuel injector lifespan. The AirDog system uses a two-stage, dual-filter design which pulls entrained water and air bubbles out of your truck's fuel system to eliminate practically all of your fuel system problems all in one place. The AirDog system is able to pump 150gph and is perfect for stock to mildly-tuned Super Duty trucks (500-800 HP at 10 psi).

Replaceable Filters

The AirDog system installs right into your truck's fuel system and comes with all the necessary lines, brackets, hardware, and instructions you'll need for a straightforward installation. The kit comes with a wiring harness and 1/2" fuel lines as well as an OEM style quick-connect fitting. Both filters on the AirDog system are easily replaceable to keep your truck running at its strongest with no hassles. Unlike other air separator systems, the AirDog resists gelling in cold climates.
