Air in Diesel Fuel can cause Retarded Injection Timing, Decreased Fuel Mileage, Decreased Power Output, Rough Idling and Noisy operation as well as Increased Exhaust Emissions. There are a number of factors that contribute the problem of Air in Diesel fuel. Some of these include:

The AirDog from PureFlow Technologies offers a solution to the Air in Diesel Fuel problem. It also provides additional fuel filtration and water separation.

IMPORTANT NOTES:

The AirDog does NOT replace the factory (or aftermarket) high pressure electric fuel pump on Ford applications. The AirDog outputs 10psi in Ford applications, a high pressure pump to step the pressure up to the required 60-70psi is still required! If you need a pump that replaces the stock high pressure fuel pump, take a look at the AirDog II...click here!

Standard AirDog units flow ~95gph. There is a 150gph AirDog available for those running extremely large aftermarket fuel pumps with flow rates in excess of 75gph at operating pressure. We don't recommend it's use unless you're sure you need it. Many of the commonly used aftermarket pumps (like the Aeromotive A1000 and Fuelab 41401 for example) will work just fine with the 100gph AirDog. We recommend taking a close look at the flow curve for the pump you will be using, if the flow is below 75gph at the pressure you will be running, the 100gph unit will work just fine.
