Best way to siphon gas?

First thing is to buy a siphon pump. Sucking gas sucks. Better still, your fuel filter should be changed, when you remove it gas will flow out. Just be ready with containers.

How long has the gas been sitting? Gas generally takes a year or more before it's starts become stale, but even then it will still be fine to run in the car.

Hey, change the fuel filter and let gravity do the work.

Remove the fuel filter. Attach a piece of fuel hose to the fuel line. Place end of fuel hose in a gas can. Turn on the key. Replace filter with a new one when tank is empty.

I agree, sucking gas sucks! I like the using the fuel pump to start the siphon. You can't drain the tank with the electric pump because the pump only cycles for a few seconds when you turn the key to the "on" position. I have an old mechanical pump I use to start a siphon. I put the hose in the tank and hook up the other end to my fuel pump. Place the pump on the ground with the arm facing up. Then step on the arm a couple times to start the siphon. It works great!

Yeah...gas probably isn't in the best of shape at this point, but it should start. While it's probably a good idea to drain the tank I'm not so sure that's going to get the car to start, your injectors are probably in bad shape having sat for 3 years.

And keep a bottle of mouthwash handy.

I think you have a problem other than the old gas. it
should still start and run (maybe poorly).
Siphoning? Thirty years ago I bought an electric fuel pump,
and put a long cord with clips on it. It's been handy
on a number of occasions, most recently to empty the
as out of my boat tank so I could replace the tank
(E10 was eating up the old tank, thank you Archers
Daniels Midland and the congress you bought off).

That's true. I should have been more specific. GM usually provides a "fuel pump test connector." When you jump 12v to the connector the pump runs continously. On the 1986, my Factory Shop Manual says the connector is terminal "G" of the ALCL connector (OBD I) under the dash. You would not have to turn on the key.
You can disconnect the fuel line at the filter, have a few big fuel cans ready, and run a piece of line into the can. Now run 12V to terminal G on the ALDL.....your tank will evacuate very quickly. Be ready. Also be ready to yank the wire out when the tank gets close to being empty or you will burn up your fuel pump......they don't like to run dry.
Quick, easy, and safe.

Get out as much as you can, but don't let the pump run dry. The second it starts sucking air, cut the power to it.

You won't be able to get it all out anyway. Get it down as far as is practical, and then fill the tank with fresh fuel.
Even after three years of sitting, it still should have banged a couple of times. Did you check fuel pressure? Modern gasoline doesn't deteriorate nearly as quickly as some people think.

Try giving President Obama a call. (He's been sucking the whole country dry)
