They might be referring to the tank venting system, if it stops working the tank will develop a vacuum on it and then if the vacuum is high enough the fuel pump can't pull fuel, there is a slight vacuum on the tank when the engine is running but it is regulated. If the fuel pump is actually locking up then you have a bad fuel pump.
