Chevy Aveo 2005 Leak at engine to heater hose (needs replacing) Cant reach backside

[Aveo-Man4]

I need to replace the engine to heater hose, my (tear/rip in hose) leaks exist just behind the clamp.
I'm having difficulty replacing this because access to the engine backside of the hose is difficult.
I drained some of the radiator coolant so the the leak does not happen currently but cannot drive it.
My Question:
Do I have to remove the airbox, throttle body and intake manifold to get access to this hose anyone? Is it possible to get access from the top or underneath of the engine with removing all of this? I have never removed the intake manifold so does anyone know if its complicated or not i.e. gaskets replacing, fluids leaking.
I was going to remove the fuel pump fuse, run the car till it stalls to rid the fuel rail of gas. I also cannot find a repair manual hardcopy so any suggestions welcomed.

Much appreciated.
