Well fuel pump only go into the tank one way and the sending unit can only fasten onto the pump one way... Idk but i'll show you what it looks like assembled:
Zoomed in on the sending unit electrical board:
This is the one I pulled out of the tank when no fuel level was registering.....
I was hoping to be able to pull the old one out of the tank but it was nowhere to be found when I pulled the fuel pump out to replace it... thought maybe it was interfering with the current one but the fingers would be at the bottom of the tank and the board is in the middle of the pump
