4age fuel line help pls

Hey, i've swapped out my 4ac from the ae82 and dropped the 100kw 4age in and i've swapped the fuel lines to the new fatter ones but im not sure which ones go where there are 2 smaller ones breather, and return? and then the bigger one which is the main fuel line. With the two other ones where do they hook up to?
on the old ones one went to a pipe at the back of the car and that looked like it when up towards the filler then came back down and split into 2. I'm assuming that one of the two pipes gets hooked up the bottom of the charcoal canister, im guessing this is the breather? and the other one, the return?, to the engine where there is that little diaphram thingy. but im wondering which one goes up and splits into the two pipes at the back of car the return? or the breather?
Cheers for any help

all three pipes are seprate, there is no two in to one pipeing, use the one at the charcoal canister as the breather, the small one on the fireall can be used as the return from of the fuel pressure regulator. Alternatively if your worried about return flow you can swap these two, keep the exsisting fuel pickup as just that.
at the tank end just get somone to blow down one of the two big lines to determine which is the source and which is the breather, and dont mix them up when you install the pump.

yes all 3 lines are separate. BUT at the back of the car, one of the old 4ac fuel lines hooked up to a rubber hose pipe that went up along side the filler up towards the filler cap and then came back down as two pipes. ie blow air down one pipe at the front of the car which is connected to this rubber hose and the air comes out two pipes at the rear of the car. thats what im confused about or should i just ignore that completely and just plug the return and breather pipes to the fuel tank directly?
Thanks again
