[spic21]

drain plug... get as much of it out as you can... then fill with 93...maybe something extra cough* xylene cough*

sweet didnt know they had a drain plug on them. that will be much easier. i googled xylene. what is it for? does it help clean tank. and how much do i need for lets say 5 gallons gas. dont want to fill it yet dont even know if it will run. also what about fuel in lines?

Mine sat for 5 years before I finally restarted it. I had to change the fuel pump anyway so I drained all the old crappy gas, dropped the tank, flushed out all the old remaining gas and sediment and let it sit out to dry for a few days before putting it back in. The drain plug is on the drivers side (24mm bolt, i think). The one in the middle is what holds the fuel pump to the floor of the tank. If you drain from the one on the side, there will still be about 1/2 gallon or so in the tank so it may be worthwhile to drop it and clean it out real good.

I have a 96 gst didnt see a drain plug but instead i pulled up the back seat and removed the cover from the floor pan and fuel ga and rigged up a pond pump with a hose attached to it to suck it all out. alot easier than dropping the tank.

Definitely drain it

My car's been sitting about a year and I anticipate having it run in a few months. I know that I should drain the tank, but what do you do with all the old gas (about 3/4 tank....)?

I also changed my fuel filter and before I put it on I pump gas through the lines

deff drain it
xylene is a paint thinner that ups your octane depends on how much you use. i use toulene personally its cheaper and easier to get in my area

yeah clean as much out as you can. . gas starts going bad after about 30 days

I had about 6month old gas in my car and it wouldn't start. Drained it, then put some new 93 in it and started right up. Just my $.02

Well, check with your municipality or county. Up here in Jersey the counties all have their own hazardous waste drop off center. A lot of mechanics I know have been installing these power burners for heat in their shops that burn old waste oil and various other fluids. They usually only want a quart or two of gasoline as it changes the way all the other crap burns (supposedly clogs up the works of these burners or something). 3/4 tank is quite a bit of gas. It may take you a few trips to get rid of it.

I had filled up the tank for a 270 mile trip and the car died about an hour into it. If I had known the car was going to sit for this long I would have siphoned most of it out and put it in another car.
