I'm going back to a stock fuel pump from a walbro and i need a new black o-ring that goes on the pump where it plugs into the assembly and the spacer that also goes in the same spot...

Do you know if this comes in the walbro install kit and that's all i need to get or does anyone know the part numbers?

 

Go to Mitsubishi, and ask for the grommet, that goes in between the fuel pump and the housing. The grommet just sits between those two. When you push the fuel pump in, the grommet will squish, and create the spacer, and the seal all at once.
