Is it the evap connection? Can it be plugged or should it be vented? Or am I completely wrong?

You are correct on the feed and return lines. The tank DOES need to be vented somehow, so the center one can be run to a vent if your tank doesn't already have one. I'm assuming that is a Camaro fuel pump/sender assembly? If so, they are internally regulated and don't need the Vette regulator.

Edit: The more I look at it, that looks more like a truck pump/sender assembly. In which case you DO need the Vette filter/regulator.
