The City of Huntington Beach Fire Department has installed six AirDog units onto our Pierce Arrow XT engines with Cat C13 power plants. We were having problems with fuel injectors failing due the amount of heat and significant fuel aeration in the fuel delivery system. Much of the problem was determined to be caused due to the distance between the fuel tank and the transfer pump. We reached out to PureFlow Technologies to see if they had a transfer pump that could be incorporated into the existing system near the fuel tank. They advised me about their AirDog system designed for our exact problem. Since we have installed the AirDog systems, we have had no signs of injector seal issues and no injector failures. In addition to having a quality product, the staff at PureFlow Technologies have been very supportive and are very knowledgeable about today’s fuel delivery systems and their inherent problems with aeration. Thanks to PureFlow Technologies and the AirDog, we feel that we have taken a step in the right direction to solve what has been an industry wide problem that is costing fleets a lot of money and making OEMs null about the issues.
