fuel pressure drops at wot

[lenzhotrod]

Are you not supposed to plug off the upper bypass? I do not own an Airdog unit.

i dont know what you mean by upper bypass?

[lenzhotrod]

Your upper filter housing has a built in regulator. Look in the 6.0 bible.

Ive been useing the blue spring since ive had an airdog II. Is this not what is suposed to be done?

[lenzhotrod]

I would not think so. Why regulate it twice? Your fuel volume is marginal to begin with. That is why better systems flow thru the head and then regulate the pressure.

well im gonna try taking the guts out of the fuel bowl regulator and adjust the pressure at the AD2. ill be reading fuel pressure from test port. hope this works till i can get the rr kit.

I think you will be going backwards if you do that. You will allow all your fuel to return to the tank. Just my thinking out loud. I would think you would want to plug the factory retun. But then again, I do not have, and have never looked into an airdog unit!!!! You might want to get help before you do something wrong on this.

ill be capping it off and returning out the AD2 to tank.
