If you do replace the fuel pump, be sure to flush the tank and replace the filter, as Ford recommended in a recent service message.
Apparently there is some kind of gunk in the tank clogging the pump intake screen. We've seen a few in our shop, and sent them to the dealer because its covered under warranty.
We have heard that the gunk is either molding flashing from the tank, or some part of the pump itself is deteriorating.
