Final chapter (I hope)
A very small hole in the new in-tank fuel line was leaking only when under pressure. replaced the week old stuff with some more bought at CarQuest rated/printed the same and it fired right off.
It seemd to be getting worse as time went on making the origional testing void. I started from scratch again and found the low pressure condition that wasn't there before. When no pressure was on the hose it worked normally, but when any restriction was there it blead pressure from the leak.
