After stockpiling parts, bursting a fuel line, and a little elbow grease the Sub is done for now. I went ahead and pulled the turbo to get to that bank of injectors, also in hope that the turbo fairy would show up too, but no such luck. Replaced all return lines with clear, finished the FTB, new tuna can, and K47. Not sure how it happened but also managed to kill a PMD while it sat. Used the "do one side of injectors then run it" technique and all went well. Instant improvements were noticed in starting, running, response, and pick up. No super seat-of-pants power, yet definitely a difference between the 145K injectors with stock supply lines and the new injectors with the FTB.
