When you guys converted to the 4.0 on a 86-88 BIIs what did you do for the fuel pump? I have an Explorer fuel pump in the tank and still have the rail pump on the BII side. I put the Ex pump/sending unit in to fix the fuel indication problem I had but now the truck just started bogging on me like it is not getting gas. It was runing great before I put this pump in so I'm thinking the pumps are somehow fighting each other. Anyone have this issue before?
