I took out the tank on My 96 Jimmy 2WD last night and when I dropped the tank to remove the fuel lines, they all broke off. Now I have 3 lines hanging down. Do you guys know by chance where they go when I get my new pump? Thanks in advance

Your 3 hoses are:
Fuel pressure
Fuel return
Tank vapor for emission control.
Since you have the tank out it should be pretty easy to sort them out.
The largest diameter is the fuel pump output.
I can't swear to it, but I'll bet the vapor line is smaller than the fuel return.

are these three sizes going to correspond with the fuel pump assembly? it looks to me that they are all the same size on the fuel pump. I just want to make sure they are going to get plugged in correctly. I would hate to have to pull the tank again just because they are plugged in wrong.

I do not believe they are all the same size.
This is a guess, but the output is probably 3/8", and the return 5/16". I am not sure about the vapor line size.
You can follow the vapor line to the canister valve to identify it.
The larger line on your fuel manifold (the one with the tire valve type pressure fitting) is the pressure line, the smaller is the return.
When you have your pump out look at it.
The line coming out of the center of the pump is the pressure out put.
