When a car is exposed to repeated temperature changes around the dew point and the tank is usually left below half full, condensation inside the tank causes rust and creates lots of debris in the tank. In other words, the new pump may have sucked up enough preexisting crud to plug it up again. This is less likely to happen in say, California or Florida. There will always be some particulate fallout from the gas itself, but not the large ammounts of rust solids.
If in doubt, check fuel pressure.
You can clean the intake screen and discard or clean the sock since the pump is most likely fine.
Take the time to clean the tank out, and keep more gas in it.
