P0172 bank 1 running rich.

Injectors, coils, fuel pump, IAC valve, TPS, coolant temp sensor, all 4 02 sensors, cats etc. all replaced. Has high fuel pressure; (spec is 49 +/-2) at 60 PSI and needle bounces around. Replaced fuel pump twice thinking the regulator was failed. Tried to buy the OEM fuel pump but it is discontinued, so bought the Delphi brand. Any help would be nice. Thanks.
