The oil pressure is what tells the injector to fire, the #8 Long Lead injector takes a double sip of fuel to compensate for the oil pressure issues. But since the #6 fires right before #8 the oil pressure is a little low and can lead to problems with #8 injector.

The HPx does even out pressures across the heads, and allows #8 to get a little more pressure.

This is in no way an attack, I'm learning here...I am engaged with Chris in an ongoing PSD system discussion in this thread https://www.ford-trucks.com/forums/1...operation.html

My comments are based on our discussions, so if something is amiss please let me know. I want to learn here, nothing more.

here is the basics of a long lead injector which is the stick thats in the #8 hole:

#6 fires right before #8, and #8 was starving for fuel, and clattering.
"long lead" means the injector stays open a fraction longer, giving it a better chance to fill with fuel, and run quieter and smoother. Ford claims it was for customer satisfaction only, and didn't affect emissions or longevity of the engine when they swapped out the #8 for the AE longlead.

the regulated return or frx fix's the dead head fuel rail and supplies the head from the rear port instead of the front port (atleast in my dieselsite regulated return) so #8 is no longer starved for fuel.........

It is worth noting that the "long lead" (AE) injector is not in all engines. Some have them, some do not. I guess it was a "game day decision" of sorts.

So I am considering, after Christmas, the FRX and HPX but I will also be putting in a new fuel pump or rather an Air Dog. My questions are these

1 How is the fuel mileage with the FRX and HPX?
2 With the Air Dog do need the FRX/ would it be worth me spending the money on it?
3 How much more efficient does would/would the motor run with the HPX, FRX, Air Dog and in-tank mods done?

thanks

3) Having clean air bubble free fuel is critical to maintaining the efficiency. If you do those mods, you will all but eliminate the chance of air going through your injectors. The in-tank mods will eliminate the screens that get clogged, and help eliminate the air being sucked in. The Airdog will filter and remove any air that could be in the fuel. The FRx will keep the injectors supplied with stable fuel for the burn. I would think you would see a noticeable difference in the sound and you may even feel a power increase depending on how much air you get in your fuel now. And since it is more efficient you may even see your MPG's go up, if you are watching them closely.
