These guys have come highly recommended locally and I did buy some stuff from them for my 6.0 and was happy
You have to do what feels right in your heart and what works for your situation. Let us know how the install goes!

I will let you know, unfortunately probably no pics the guy who's helping me probably wouldn't tolerate the time for pics. He's kind of old school I guess is the best way to describe it. As far as my choice of injectors I'm satisfied with it. Looking around on line briefly 225.00 each for new ones seems pretty fair. I'm supporting a local shop, able to pick them up, he charged me no core charge just asked me to bring them back asap. I debated going over sized but I've never had an issue with any of my 7.3's pulling the way I want and I figure a new set of injectors alone I should see an improvement over the current ones with 226k on them. Hopefully I don't regret that decision. I'll keep,you guys up dated. Hopefully this corrects the disappearing oil. Thanks for everyone's help.

The AE won't be needed however if you fix your dead headed fuel supply, by adding a regulated return. This puts an end to the #8 injector being at he end of the fuel road, so with improved flow the AE is no longer needed to compensate. Again, it all comes back to your future thoughts on upgrades. The regulated return doesn't really give you much by itself, but as a foundation it lets your injectors do more if you ask more from them, i.e., get a chip, bigger turbo, exhaust, etc.

What I don't understand here is...what makes #8 any more 'at the end of the fuel road' than #1? Both sit at opposite ends of their respective head from the fuel feed and, actually, #1 has twice the run that #8 does (If I understand correctly).

See the firing order? 6-8 are sequential firing. #6 steals the fuel, and leaves #8 low while it replenishes. Fuel for #8 has to go past #6 and some of it is consumed by #6 firing.

At least that is what I understand

Ok but if I do regulated return later the AE injector really won't change anything but for now it will compensate for the situation. Correct? Right now my funds are getting depleted especially with a chance I may need an hpop yet. On a good note I was able to fix my wife's excursion by replacing the ipr, which I had. So that saved me some $ to help compensate the expenses here.

Now that explanation seems logical.

The AE injector wasn't OE at first, it only became an issue for those who complained about the noise or such. It was a TSB for awhile, if the customer complained. I wouldn't be surprised if a lot were replaced simply because it was a free service the dealer could perform at Ford's expense during routine service calls.

At some point it did become an OE installation, but I don't know when. I also don't know, as you mentioned, if it impacts performance if you were to get a chip later.

Riffraff has their FRx, not nearly as expensive, or I wouldn't have one.

The Riff Raff Fuel crossover is a very affordable and easy fix for the dead head issue. Mine works great.

Well we started the injectors last night. Have all 8 new ones in, just have to seal it back up today. 6 out of 8 had very badly deteriorated middle o-rings. Cylinder 7 had just a tiny bit maybe. 8 had none. 3 and 5 were by far the worst with the rest close behind. Cups all looked really good. Cylinder 5 had a non oem injector in it. The rest I believe are original. I took a few pics of the o rings I'll post when I have more time.

Quick question, any opinions or thoughts on what would cause these o-rings to go bad in 16,000 miles. Other than a bad install by the previous owner? Poor choice in o-ring manufacturer?

Both of those are the top 2 reasons. You are on the right track, we look forward to the pictures.
