Does said fuel tank use same sending unit/fuel pump/EMS hole as my '94 Bronco's sending unit/fuel pump?

Not counting mounting the fuel tank and filler neck location; is it a simple swap/plug and play-functionally?

The FPM is unlikely to sit deep enough in the tank to reach the bottom. I have a FPM from a 94 F-150 and it is several inches shorter than the 33 gallon Bronco version. I would have had to put the pump on some extension to make it work. Also the angle of the sender was such that my extension would have had to have a bend in it to locate the pump in the tank well. The stock FPM is already a snug fit in the 3 5/8" hole so I was doubtful an extension was going to make fitment any easier. The fuel level sender had the same challenges too.

Yes the hole is the same. But as noted above, the whole assembly is built for each specific tank: depth and angle and whatnot.

Good points.

Can I simply use the sending unit/fuel pump/vent port from the front fuel tank, then?

my understanding is the front take uses the same pump as bronco but with different sending unit. the rear tank uses a different pump. all 3 use different sending units. i could be wrong

JBG has the sending units

If you already have the parts, its worth a shot. Most likely a shallower float arm set up will show empty when there is a few more gallons of fuel still in there. The fuel pickup has to go almost to the bottom of the tank though.

I know my '88 tank has three lines (ports) and they are flat to the top of the tank as they would hit the sheet metal floor if they pointed up. I don't what a '94 bronco tank has.
