Coolant hose is not an acceptable replacement. You must use a fuel rated material. Long before the coolant hose fails and leaks it will start shedding rubber into the tank. This can competely foul the intake of the fuel pump and cause it to fail.
If the OE hose is too damaged to use you'll need to find a correct replacement. Fierostore is one of few places with the correct material with the needed bend formed in it. The bend is too short a radius to use most straight stocks.
