YES! I have a big oil stain in my driveway because my catch pan was doing it's job in the wrong spot. Which means I dumps about a cup or two of oil on the driveway, before I noticed my catch pan was in the wrong spot.
Lift pumps are pretty robust on these cars. I would suspect that your primer pumps are letting air in.
You say you cleaned the tank screen, you could rule it out just to be safe by switching the supply and return lines in the engine bay to see if it solves the problem. If not then you know it's not the tank screen.
