Blaster Yamaha 1100 help

Location

I'm currently gathering parts/planning everything out for my 1100 blaster and have a few questions.

On my 1100 motor, there seems to be 2 separate fuel lines that are on the carbs; one is hooked up to the fuel pump towards the back of the motor and the other is sticking out near the throttle/choke cable mount. Where should each of these hoses be hooked up?

Also, my coupler on my midshaft is different than the coupler on the 1100 motor. Are the couplers interchangeable i.e. will a coupler from a 701 fit on the 1100 crank? Which type of coupler should I use?
