Please explain regulated return system, Airdogg?

Okay, I just learned as much as I can about the fuel system in the 6.0 engine. I would really love to know how the regulated return works and how the top of the line air dogg works. Any help would be greatly appreciated. thank ya.

A RR system removes a set of plugs at the back of the fuel rails. You plumb the fuel to a regulator then to the return line back to the tank. The concept is to know the fuel pressure AFTER the injectors and maintain it.

The AD2 allows you to regulate the pressure BEFORE the injectors therefore supplying the recommended 55+PSI fuel at all times.

If you get one you don't need the other. I recommend a AirDog system and a fuel pressure gauge.

Thanx, I appreciate the info. Is the AirDog a replacement for the factory fuel pump and filters, or is it added to the system?

The AD100 or AD150 is added to the system. The AD2 (II) is used as a replacement to the HFCM (stock pump on frame rail).

Does the AD2 use the factory filter or is it proprietary?

The entire HFCM is bypassed. So NO, it would not use that filter at all. The secondary fuel filter (engine mounted one) could still be used though. Or you could remove the standpipe in the housing and run it with no filter in there.

The water sep. and filter on the ADII will filter plenty well enough.

I think I get it. The ADII has its own filter, presumably proprietary and replaceable. Thanks.

Yes the ADII has its own filter and water seperator. They are not prorietary and are replaceable. No real need to change the water seperator just drain any water out of the petc0ck.
