When you say no fuel on the fuel pump side, you are referring to the return line, correct? Also, how are you adding fuel to the fuel pump side?
As far as the regulator is concerned, is anything preventing it from getting fuel? I ask because if you are getting fuel on the return side, where is it coming from if there is nothing on the supply side.
I attached a pic below of the fuel pump sending unit. It shows the return lines and the supply line. Which ones have fuel, and which don't? Also, let me know if that is what you are seeing. That is the US version. I just need to be sure we are on the same vehicle. LOL They change things based on destination.
I will watch for your reply.
