Don't do that...
Drain the fuel tank completely (there's a drain bung on the bottom) and put some fresh fuel in. Then remove the return fuel line in the engine bay (not the one on the fuel filter, the other one) and put something under it to catch fuel, jumper the fuel pump check connecter and turn the ignition on. The pump will then push the fresh fuel in the tank through the fuel lines, filter and rails, pushing the old fuel out in front of it. Run it for a minute or two to be sure.

I coudln't agree more, doing it this way not only gets the gas out of the tank but also the old gas out of the fuel rails so when you try to start it the fresh gas is right there. But dont let the pump run dry, the gas actually lubricates the pump and letting it run dry could damage an otherwise good pump.

Good point. Realistically there will be well under half a litre or quart in the lines and rails, and the stock TII pump will move ~2L/min when doing this, so running the pump for 30 seconds is probably all you really need.
