Ok I am finally putting in my fuel pump. The old pump has a black and a gray wire connected to the pump. The new connection I got for the Walbro 340 has a black and a red connector with nothing on the other end. I read about the 86 haveing spade connections on the other end from the connection to the pump. That's what I have. I don't have a problem with crimping the wires to the connector but, is black to black and gray to red????? which wire is the hot one?
