2002 fuel sender connector HELP

I have found only one video showing the removal of the black fuel return line and it shows the dude lifting the two tabs and sliding it off, I tried this and mine does not want to come off, another video without actual demonstrations said to pinch the line with needle nose pliers, not the best description.

Is there anybody out there who has done this before, I have spent hours trying different ways, I am so pissed that I am about to cut the line and figure this thing out on the bench.

ullout:

Thanks,

Corky
