Mike, there are drain plugs on the gas tank's of at least my sol and integra.
As for siphioning it. I found an article on line that used some fluid property, gravity, and a few other things that made siphioning gas possible without having you get a mouth full of gas. I tried to do it, and it really doesn't work because honda did a cleveler little thing and put a little "trap door" towards the bottom of the filler neck. You can stick the hose about 24-30 inches in there, then it just doesn't want to go any further.
Make sure that you do this in a very well ventaled area with no electrical stuff going on. If you turn on a light and something arcs...well nice knowing you.
Once you actually do think you have it done, run some fuel system cleaner, run a tank or 2 through it, ect. If gas sits for a very long time, it is going to turn gummy.
Also, with the "undo the fuel filter to fuel rail method" that would be extremly unsafe. Now, your running a stream of gas with a ton of vapor, and your using your electrical system. when you drain your gas, you do not want the car to even have the battery hooked up.
