The way I do it. Rag around incoming fuel line. Disconnect and let it drip.

The less messy and proper way. Remove EGI fuse from engine bay. Start the engine and let it die. Fuel system depressurized. You will still have some fuel spilling out...

Another way. Pop trunk, disconnect fuel pump electrical connector. Crank engine let it die. Fuel system is depressurized.

If the car is left unattended overnight, the fuel pressure will have been reduced so as to not cause any problem other then the residual fuel.

Remove fuel pump relay, run engine until it dies. Remove gas cap too if you have the stock EVAP stuff.

That is the 'proper' way to do it, but I would honestly just remove the gas cap and let the fuel squirt out like others have suggested.

I prefer to run the engine, stick my face really close to the fuel rail, then pull the hose off as quickly as possible.

But really, the pressure dissipates eventually. So if the engine hasn't been run recently, you'll just get a little bit running out. It is not a big deal, but try to keep the gas off of painted surfaces.
