Fuel leak. Please help.

[Hubert]

I have a 89 hatch that's leaking on the return rubber fuel line near the gas tank passenger side. Most possibly because its dried and cracked. Is it possible to replace line without dropping the tank and what size hose is needed to replace? If the line is a return and leaks only when the car is running, am I expected to have what is in the tank to pour out until empty?
