The gray wire is the power to the fuel pump and black goes to ground- dunno where the other black wire goes-no wiring diagram for the fuel sending unit-sorry

Dunno, you just have to backtrack your work if its working prior to replacing the pump-

The Gage dis work prior to replacing the pump. By the way thank you for your help. Does this seem like a wiring issue or maybe the float?
