Q for the fuel system Pros

[Fox Hunt]

So after reading tons of threads on three forums. I know what I want but need some advice a to whether I can our not. Was going to build my own fuel system but scratched it to gamble on an
Airdog II because of the air removal. Now here us my question- can I build a setup using the airdog, bypassing the stock fuel bowl regulator and eliminate the dead heading without another expensive regulator? Will a crossover line fit my needs? stokin6L told me a fixed orifice is what ha been recommended to him, but honestly in unfamiliar with what one is. So feel free to come in with your ideas and if I'm just dreaming or some way to make this happen.

If you want to bypass the factory filter bowl the best way to do that is by running a fuel line from the AD to a y-block and then to the front of the heads. From there you can leave it alone or do a RR of the back of the heads to a regulator and back to the tank. A fixed orifice is really the same thing as a regulator but not adjustable. The main thing would be to turn the AD2 up as high it could go and use the second regulator as the controlling one. If not just use the AD2 and have your fuel lines dead head at the back of the cylinder heads. Those are really the only two ways to do this.

Thanks thats what I needed to know. May just let it dead head for now and then get Dozers rr when I get closer to injectors. Just curious how is a crossover line supposed to help? Out send like to me the fuel would just dead head in the line then.

yep a cross over is a waste and the fuel dead heads in the line.

Thats what I figured.

There really is nothing to be gained by adding another regulator at the back of the heads. Run it from the ADII to the heads and let the ADII regulate it. It is still a regulated return and works great that way.

Pgreen are talking about just running the fuel lines to the front or through and out the back that you dont need another regulator?
