Is there a sucking noise when you remove the fuel cap?
I would think that the half tank issue is probably a coincidence. It might just be the fuel pump or a problem with the sock. The pump picks up from the bottom of the tank and the lines inside are metal. I've never seen one with a hole in the lines inside the tank, but then again, there's a first time for everything.
(well almost everything I got to thinking on that comment)
