Air Dog Fuel Preporator® II For Caterpillar

Air Dog Class 8 Fuel Preporator for Caterpillar 3406 A, B, & C




For Caterpillar 3406 A, B, C

Each AirDog® Fuel Air Separation System and installation kit, except for Universal Models, is engine specific. 

With AirDog®'s NEW Micro-Processor Fuel Filter Monitor, the operator now has peace of mind from real time knowledge about the status of his fuel filter and water separator. No more wasting time and money replacing a clean filter or driving with a dirty filter after unexpectedly taking on dirty fuel.

The AirDog® air/vapor return line can now be connected directly to the existing engine fuel return line, reducing installation time and materials. The necessary fittings and return line (for most installations) are included in the kit. No need to waste valuable time and money installing an expensive "second return line system".

Additionally, the Cat hand primer pump, with very small and flow restricting check valves, is no longer needed as the AirDog® is a self priming system. A replacement cap for the hand primer pump is included.
