Either way. Its running now. Thank the magic man in the sky.

I do... we add a little bit of fuel line to the pumps we sell for various bikes and I trust only one fuel line currently available. It's the braided shiny stuff from Helix racing. I've had a few long chats with the owner-guy there. They do colors and we are buying all of their spools of "not red" defect hose for our application. It's kinda pink. The Parts Unlimited link I put in is for clear. Any good local shop should have this stuff.

OK I'm officially closing this thread unless anyone has any more insight.
Since my starting issues, I have:
-Replaced sparkplugs
-Replaced Fuel lines
-Checked EVERY mother freaking connection
-Switched in/out fuel lines (this turned out to be the problem but not for the reason you would think)
-Replaced QuickDisconnect O-rings (Thanks Chris at CA Cycleworks for getting them to me fast, I really appreciate you guys)
None of this worked until I decided to look inside the tank.
The culprit turned out to be (and I am 100% sure that this is the issue):

To Chris' idea of the fuel system being a "closed loop", you may be right (I still haven't verified this and will not). It may not matter if you switch around the fuel lines, HOWEVER, once you switch them, you are shooting fuel through hoses one direction that used to flow in a different direction. What does this do? This loosens debris and sends it to the (you guessed it) FUEL FILTER.
Remember that PSHHHHHHHHHH sound instead of the ZZZRRRRRRRR sound that I mention that was a new sound when turning the ignition on for the fuel pump to prime??? well THAT was the problem. the pump was shooting fuel through a clogged filter because I had switched the lines around. The filter was soo clogged that the pump forced fuel through and cracked the cheap ass plastic filter. Fuel being forced through this small fracture was the PSHHHHHHHHHH sound, not pressuring the system, and simply pumping fuel from the tank back into the tank via the filter leak without getting to the throttle bodies.
I replaced with the suggested Napa part 3032.
I've ridden for a few days now and the bike is running better than it ever has.
For those that hear the PSHHHHHHH sound. Check your fuel filter
All this just to wrap my exhaust.
