Yes, I believe the difference is how the connections to the fuel line go.

The only difference is which way the connections point like zieg85 said. I've put the wrong one in once when I needed a tank because of a hole in the bottom and couldn't immediately get the right one. It worked fine. Just had to make a curve in the fuel lines.

     You also need to know how many tubes are on yours, pickup tube, vent tube, and maybe return if yours has it.

#2: There is no such thing as impossible, it just takes longer.

The prices for a 3 outlet are almost half the price of the 2, is there any way to make a 3 outlet work like a 2?  or should i just quit being

Yes you can make it work.
On the truck which line isn't there? Return or Vent?

The 3rd hole is the tank vent, you would have to have a cap that vents.
