Charlie, the old man that designed the original Diesel Fuel Preporator has fairly recently gotten just the class eight end of Air Dog back. The folks that bought it were struggling with the class eight pumps. The motor would not hold up due to seal failures at the pump drive failing and allowing fuel into the electric motor. The reason for that was excessive run out on the rather long motor shaft. When Charlie took the Class eight units back over he redesigned the pump drive to isolate the motor from the pump and eliminate the fuel contamination that was causing the failures along with zeroing out the motor shafts run out. The result is an amazing improvement of performance and dependability. The new units are very quiet and smooth. Charlie also designed a protection module for the motor that censes filter restriction, and when that restriction raises the amperage draw from the motor it shuts of the motor down so it will not over heat and self destruct. I choose to incorporate a cab mounted fuel pressure gauge in conjunction with CharlieCharlie's new system that also has a in cab monitor with colored lights that advise when a filter change is required. I have not used the FASS and have nothing to say about it one way or another. Charlie has always treated me very good and it has been a pleasure to work with him since my first Diesel Fuel Preporator in 1997. He also has a list of readily available name brand filters to fit his units if you need, or if you can get a deal on filters somewhere else.
