From my knowledge of these trucks, I am thinking fuel pressure regulator will take care of pressure differences. So I am going to use a bronco fuel pump, that way I will know there will be enough pressure. Right now I am undecided about closing off sending unit to front tank or what. If there was a temporary way, I would be all for it.

As for the piece that branches off of the sendingunit/fuelpump on the outside, I haven't found a piece like that and wouldn't my old f150 have a piece like this to use?
