I know not a ranger I have a 93 f150 4.9l with dual tanks and the front tank runs great without issue when you switch to the rear tank it will run fine for a min or 2 but then seems to loose fuel pressure until you swap back to the front tank. it will idle all day long on the rear tank just can't drive it. both pumps are new fuel filter is new fuel pump relay is good.. when I check power to the rear tank it is @ about 14 volts running.. any Ideas ?
