Check your cap, you should be using a vented gas tank cap. It is possible for a good strong fuel pump to partially collapse a tank without a vent.

To repeat, for an original or of-the-era fuel delivery system your tank must be open to the atmosphere thru either a vented cap, or other means. Not saying your problem couldn't lie elsewhere, but that's where I'd start. If you determine you had a non-vented cap, check to see if the vacuum has collapsed the tank.
