Fuel filter bowl is now gone.
You forgot to tie in the return line from the ADII. Tying the ports on the back of the heads to a Y and returning to the tank as above would result in an unregulated system where the fuel would just run through the heads and back to the tank in a big loop. I doubt the truck would run this way.
Supply from ADII to a Y to the head port banjos. Block off the front of the ADII loop hardline that goes to the fuel bowl. This would allow you to take the fuel bowl out of the engine bay altogether as I have done.
If you just want to eliminate the oem FPR from the picture so you can just have the ADII FPR regulate the system the simplest way is to take a coke can and cut yourself a disk the size of the return line fitting on the factory FPR. Put that disk in the return line and reattach the return line to to FPR. That's it. No more oem FPR function.
