When you replace the fuel pump always use an OEM (Original Equipment Manufacturer) unit. Have your fuel pressure checked to make sure the new fuel pump is working properly. Have your computer scanned for trouble codes, the runability problem could be as simple as a tune-up.
Regarding the gauge, it sounds like your sending unit is bad. If the sending unit was replaced with the fuel pump then the gauge is bad.
