unscrew your filter ... turn the key switch to the on position lol and get back.... the feul pump should pump most of it out but this way is going to make a mess man....

I tryed that already

Everytime I hit the key...it pumps out like a table spoon at a time...I have to keep turning it on and off..on and off..in order to get any gas out. It doesn't keep pumping....

take your fuel pump relay off and jump the lead from power to the pump and it will run as long as you have it there.. just have to be careful you dont burn ur pump out..

Go under the car and remove the fuel lines, one of them siphons the tank dry when you do this (don't remember which one though) and will leave you with about a gallon of fuel in the tank. After that you'd need to remove the tank, take the sender out and roll the tank over to get it all.

This is how I did it.

Disconnect the fuel line at the point where the rubber line meets the intermmediate hard line in the engine bay. (it goes hard line, rubber line, hardline to hard line on rails under the hood).

Next, take a 3/8 barbed brass fitting, wrap it in teflon tape. and screw it in to the fitting on the end of rubber line. Now take about 4 feet of rubber hose, and clamp it to the barb.
Next, take a wire and jump from 12V on the fuse panel to the "F" connection on the diagnostic plug. That will run the pump constantly as long as the ignition switch is on.

This method is a hell of a lot easier that it sounds. You don't even need to jack the car up, or worry about getting gas all over your arms crawling around by the fuel filter.

I managed to syphone all but a couple drops out of mine. When I dropped the tank, I had only a few ounces left.

Hey 406GTA, that would be pin "G" on the ALDL, pin "F" is for the transmission torque converter clutch (TCC).
