Keep on Truckin' with a Pureflow AirDog Fuel Air Separator
Clean up diesel fuel with a PureFlow AirDog Fuel Air Separator. Dirty, water-contaminated diesel fuel can quickly cause havoc in your engine, reducing power and mileage as well as shortening component life.
The AirDog systems move your fuel through a state-of-the-art air removal water separator and fuel filter to remove water and particulate contaminants as well as separate the entrained air/vapor. Your diesel fuel will now be free of power-robbing contaminants and flowing at maximum requirements.
The AirDog II-5G systems have a diaphragm-style fuel pressure regulator to boost-reference the lift pump from 7-70 PSI. A demand flow design allows the pump to only send the necessary amount of fuel to the engine.
PureFlow AirDog 4G and AirDog II-5G systems are available for late model Dodge Cummins, GM Duramax, and Ford Power Stroke engines. Summit Racing also carries replacement filters, pressure regulators, and lift pumps.
