Hello I have a question on fuel supply to the injector pump. I have an AirDog PF100 system on my truck. First thing I want to know is I am running the fuel through the factory filter and water separator. I changed all the Banjo bolts to AN8 1/2" fittings to do this and ran into and out of the fuel filter to the injection pump. I know that it is better to have more filtration but I wanted to know am I also creating more restriction / back pressure in doing so to the injection pump. And if i do run through the factory filter should I up the fuel pressure coming from the AirDog to compensate. I don't have a fuel pressure gauge in the fuel rail so I can't say what pressure is there. I have about 20 psi from the Airdog on an average. Also wanted to know whats the best filters to run with the PF100 system. Thank You

On the standard lift pump the pressure is only 7 psi out of the fuel filter. So if you are getting 20 from the AD to the stock filter you have more than enough.
