Got it back together again and running generally good. Its smooth, but throwing code P0170 lean bank on occasion. I can clear it and it goes away for the rest of the drive. Seems to be warm, at idle when its throwing it. I'm not sure the A/F made it through the 'gassing' so ordered another. My Bosch wideband feeding my plx sensor lived. That was nice, I can still read A/F on my gauge.
Trouble shooting the leak, we took it apart reset the injectors and rail, reassembled, same leak. Checked again the feed and return lines, nothing. Took it apart again, lots of gas on the plug so started to think stuck injector or misfiring injector. Gas was in the exhaust. That didn't explain the rail like though, we continued.
Alex found a way online to jump the fuel pump relay. This was pretty handy to run the fuel through the rail with just the injectors on. No leaks observed, BUT ... the cylinder filled with gas after a minute of running! The leak observed before, on the back of the engine, was gas coming out of the intake. We sucked out 2 cups of fuel from the cylinder (top/bottom) and left it there.
Crappy pic of relay jumping. Jump pins 3-5, and with the ignition on, the fuel will cycle in through the rail. This effectively lets you test the injector install before you drive it.
By now any question I had OEM injectors was gone. They were slightly different than OEM, had paint dots, but the crappy orings where more of a clue. After a couple installs, the orings were toast and they wouldnt seal.
OEM packaging (left) vs counterfit ones (right). Differences are of course the box vs bubble pack. The label text is different, one oring is red not black, and no paint dots.

I put it all back together again, a backfire and 20 mins to burn all the gas out the tail pipe and it was running right again.
I changed the oil, a sizable amount of gas was in the oil.
Test spin throwing the code, stuck throttle, shift to neutral + key off, popped the hood to get home, a very exciting test drive.
I cleaned the MAF, checked voltage standing, while blowing, but I've got a new AF meter on the way. Expect the nightmare to soon be over. Oh and I routed/adjusted the accelerator cable correctly.
Lessons learned.
