I am replacing my fuel pump and as I slowly lowered my tank I noticed only the fuel pump/fuel sensor wiring harness was present. The fuel pressure sensor wiring harness was not there! After removing the tank I can see there is also no harness attached to the evap control solenoid(also it is the same three pronged plug). Should I make a new harness with two female plugs? Is this what the fuel pressure sensor plugs into?

Ok are you sure you got the right pump? There is only 6 different options depending on engine size and 8th digit of the vin number and weather or not it is federal or california emissions. If you give me all this info I will look up the pump and include a pic of the one that should fit so you can check it against the one you got. It may not have the emission part on the pump from the factory. Also what size truck 1/2 ton or? Get back to me and we will see what is up.
