I'm still back at the tank, even with the pinch, as to why it's not vented properly.  It should have to be vented with fuel flowing back to the tank.  Fix the pinch, then on to the vent.  Good luck, hope it's all simple.

There are 2 vent hoses on the tank that are clear of obstructions and venting properly.
