Reuse your OEM FPR. The box says it is for all 03s, and 04s that are flex fuel (8th VIN Z).

Ok, I think I understand but I want to be sure. Here's a quote from one of the emails:" The box says it is for all 03s and for 04s with eighth Vin z. Bad wording on their part, but the correct system. Should also say 05 with eighth Vin z. 04 non flex fuels have no return fuel line, while the FFS still do."
I take it ALL 03's means all 03's with OR without flex fuel.
Another email from another person and another quote : "The box says that the fpr is pre-installed on a Vin Z only, they run at a lower fuel pressure in some cases.".
(I'm getting 3 email threads right now from BlackBear as well as your help here, Jenna. Justin is emailing me and 2 others who I'm not sure who they are but they're from tech. the amount of help you guys are throwing at me is crazy, and it's Saturday.)
So from all this I take it that I will reuse my fpr and it's up to me on how to figure out the routing of the hoses. There's the 3/8" quick connect in the middle of the passenger side fuel rail, the 5/16 quick connect on the driverside fuel rail by where the fpr goes and the fpr itself. Does the fpr go on the return line, because that's the only way that makes sense. I still don't get it but maybe I'll just go tear my truck apart and hope you guys are right, that the correct parts are here and it will work.
edit: I just had another look and I think I've got it. The fuel feed is the 3/8 quick connect on the passenger fuel rail. There's a hose and a coupler to go from there to the truck fuel line. Then the fpr goes on the return line at the driver side rail where the 5/16 quick connect is and the fpr has a small vacuum line fitting. There's a small vacuum hose on the lower intake manifold that will reach the fpr. Then the return line is a 5/16 quick connect fitting opposite the fpr and the truck's return line is flexible and looks like it will reach.

Yes, ALL 03s, with and without FF.
Yes, reuse OEM FPR and put on return line.

Away!
Sounds like you're all over it now, Red. Nice to see that kind of support. Don't forget to take pics for us to see what you're doing!

Oh crap, pics. Kidding. Of course I'll try to do my best. Trying to figure out the EVAP solenoid now, it's the last of my concerns. I want to get all my questions answered before they all get tired of me. I figure there's only so much Saturday support I'll get lol. I'm about to tear this thing apart.

Oh damn I forgot pictures, got too busy...HA! I have a ton, I'll update when I quit for the day. I tore it all down and am in the process of installing a few items including oil pressure sender, valley cover gasket, knock sensors etc. There was a LOT of stuff to remove.

Away!
Yeah there is. Sounds like you're making good progress. Just think of all that brand new stuff you're putting in!
OP

Well I quit for the day, except maybe some inside work swapping parts off the manifold. I got everything removed and began putting stuff back together. I worked from 10-5 straight through with only a coffee break and my back is killing me! Here we go. The start picture, followed by some parts I won't be needing like the Spectre CAI and my catch can. I'm pretty sure the catch can can't be used with FI but I'll check to be sure. Then I started removing electrical connectors and labeling them.

I have to do an EGR delete so I started trying to remove the 2 bolts that were in the exhaust manifold. I knew they were going to break even though I hit them with PB Blaster for days prior. I bought an EGR bypass kit but all I need is the one oval cap and gasket. then after removing all the electrical connectors and a few hoses and misc stuff I got the intake manifold off.
OP
OP
Here's a couple shots with the manifold off and you can see it's going to be easy to replace the oil pressure sender. There was a bracket with a bolt in the very back of the driver side head that was a real ***** to get off but Whipple said it had to go. It was all I could do to get it off. I figured out what the instructions said about the purge solenoid hose that goes to the evap tank. I couldn't see where the OE plastic hose went until I removed the intake manifold. There is a fitting behind the engine, down the firewall, that the quick connect snapped onto and that hose will go to the rear outlet on the purge solenoid. This was NOT clear in the instructions. And it was not visible even with an inspection mirror until the manifold was off. The belt tensioner is another item that won't be going back on.

^^This. Living vicariously. Can certainly appreciate your tenacity. Love the updates.

I pulled the water pump. They supplied a new 07-12 Gates pump as an upgrade and an AC Delco 160 degree thermostat and housing as well as a Gates 07-12 upper radiator hose. I pulled the knock sensors and of course they were filled with water and junk. The pic shows the water level on the rear, almost 1/2" up the side of it. And here's how easy it is to replace an oil pressure sender with the manifold off! I cleaned the valley after pulling the cover.

Thanks guys. I was pretty nervous before I started this. It's been a long time since I've done anything even close to this, plus it's my only vehicle except Harleys and I don't think my work tools will fit on my bagger so this HAS to work!

With the valley cover off, I took a couple close-up shots of the cam and it looks great. I took a break to look at what a mess I had going on. This is only part of it, a lot of stuff has been removed from the area. I have now replaced the valley cover gasket, knock sensors, and oil pressure sending unit. Those knock sensors aren't going to leak now. I cleaned with denatured alcohol and then used a commercial grade of Dow Corning silicone that we use at work, made especially for bonding rubber or vinyl to metals. Take that, water!

I want to do a shout-out to BlackBear Performance, the ones I trust with my cash and my truck. I purchased the Autocal as well as the Whipple from them. There's a reason I got the Whipple from these guys. Today I had no less than 3 email threads going on the same time from them as well as a PM thread and postings in my build thread from Jenna. Unbelievable support at a time when I was afraid Whipple had sent me some wrong parts and I was going to have to abort the project this weekend, and I had already scheduled next Monday off from work. That would have been very bad if I had to wait. So , yeah, a shout-out to everybody @BlackBearPerf !

Is that ever gonna be able to come off if you need to get back in there?
