The 00-01 fuel pumps were known to do this. I had the same problem with my 01. Mid 02 Ford changed the design on the basket and the way to connect to the tank to solve the issue. I put in a 02.5 tank/pump and have no more issues.
You have two options, find a 02.5 tank/pump and swap out your gas tank, or you can buy the 02.5 pump/basket and modifiey it to fit your tank. I believe that Steve at Toulsey ford can get you prices and info on doing the later.
