I want to drain my gas tank because it has 6 year gas in it.

The damage is already done. Gasoline breaks down within 1 year. Drain and flush the old fuel out of the gas tank(s). Try adding Chevron Techron fuel injection cleaner to the replacement gas. That may work. However, you probably need to remove all the fuel injectors [if it's a fuel injected engine] and have them sent out to be professionally [ultrasonic] cleaned and tested. Fords are notorious for fuel injector problems. Also do a fuel system pressure test, as the bad gas may have damaged the electric fuel pump [located in the fuel tank(s). For a carbureted engine, you will need to have the carburetor overhauled or replaced with a rebuilt unit. NEVER let a vehicle sit unused for more than 6 months without first treating the gasoline. I always add a fuel stabilization product like Sta-Bil to the fuel, if the engine will not be run for at least 2 months or more. Adding these products after the fuel has gone bad [is already old] will not help. Then it's to late. Below is a link for Sta-Bil. I've used this product for over 20 years. It will save a LOT of grief, when storing vehicles or gas powered lawn equipment. See

Because the engine turns over means your started had enough voltage to turn ON. You can easily test the voltage on the battery with a volt meter. It should be about 12.0 Volts when the engine is not running. Batteries should normally be charged every few days for about 1/2 hour each time. You can go a short time for a couple of weeks without charging as long as you don't get in to a habit of doing that. If you went for months without running your car; I assumed you had to replace the battery already or your battery would not have been able to turn over the engine or hold a charge.

The automatic door locking is the least of your problems. It might be your car did not have a battery of proper voltage for an extended period of time.

Gasoline does not age well if you did not place any additive for prolonged storage. Even the additive for prolong storage says about a 6 month period. Maybe you should take out some gasoline from your tank to see if it still looks good. I normally don't fill my tank but every 1 to 2 months (without a problem) with no additive added, but 1 year is a long time. My guess is 1 year old gasoline may have changed over time and thickened and it could have contaminated your fuel system.

Depending on how old and how much fuel is in the tank can affect your next step. If the fuel is the problem; you will have to drain the tank and possibly have someone use one of the pressurized fuel cleaning treatments. You might need a new fuel filter, and I know there is a pressure regulator to return the fuel to the tank as well as fuel injectors and the fuel rail. I have never had gasoline that old, so you might need a professional mechanic if you are dealing with old fuel in the system.

The only gasoline I trust to age over time is Coleman fuel in a sealed container (also known as white gas). This can be found where they sell outdoor camping equipment. I don't know if that will help, but I had to run 1 gallon of this in 1992 Oldsmobile 88 because there was no gasoline. Coleman fuel is ultra refined gasoline without the extra additives they normally put in gasoline.

Hi,Did you start the vehicle after you put the gas in the tank? A drain plug is fitted underneath the tank,drain the tank of gas then fill it half way or more it may run a little sluggish at firs but the amount of diesel to gas ratio will mean it will do no harm.Hope this helps.

on top of gas tank. you will need to lower the gas tank after disconecting the negative wire on battery. You should have drain plug on the gas tank on that model drain all gasoline from tank. hope this wil help

Add fresh gas and a can of Sea Foam, charge the battery, check the brakes if you plan on driving it do these things and you should be good to go.

If I were you, just take out the old gas and put some fresh fuel in. Next time, keep a few cans of SeaFoam in the car. It stabilizes the fuel for up to 2 years (1 oz for each gallon).

Since is sat so long, whatever fuel was in the tank has probably gone "sour". Old gasoline gets an unpleasant "varnish" smell to it. The only certain way to remove any bad fuel is to drain the tank, and by all means change the fuel filter again.
Another thing that happens when a vehicle sits a very long time is that condensation in the tank causes water in the fuel. One or two cans of "dry gas" along with a full tank of fresh gas can often take care of this.
The easiest way to drain the fuel tank is by disconnecting the fuel line under the hood, connecting a hose to it, place the hose in a gasoline can, and turn the key two clicks to "ON" (NOT START!) so the fuel pump does the work for you.

if it is posible for you to drain the the old gasoline out and refill the tank with fresh gasoline that would be great, but if you only have a1/4 tank and draining the tank is not posible fill your tank up with supreme gas not regular the better grade gas with the high octane will dilute the old gas and help burn off the gas when the car starts.if you have more then 1/2 a tank try to pump out the gas with a driil pump, you can buy these a your local hardware store insert hose in filler neck of the tank.you should also remove the spark plugs and with and oil can add 8 good pumps of the can of motor oil in the cylinders do not replace plugs **** with a freshly charged battery turn the engine over few time in 2 or 3 second intervals this will kleen any rust that would have built up on the cylinder walls and also lube up the cylinder wall so that at start up the cylinder wont be dry ,add a few more sqirts of oil between turnovers.Replace spark plug if old ones look bad put spark plug in and start her up its going to smoke a bit at firts **** it will stop after the oil that was put in the cylinders burns off,let the engine idle for 10-15 minutes before putting any strain on motor give it a chance to clean out cylinders burn a few tanks of gas and change gas filter it should be fine.

well first of all, it's a good thing you're draining it, because there's rust in your gas tank. Second, you're going to have to siphon the gas out, and third, use a proper technique, because i doubt that gas is too tasty

Disconnect battery,remove the tank and drain it.The fuel pump is no good now too,replace it with new.After draining the tank,let it air dry for several hours so that ALL the moisture has dissipated.After reinstalling fuel tank with new pump,safely disconnect a fuel line up at the engine and place in a container.Add new clean gasoline,and cycle the ignition switch on and off so that the fuel pump will come on and flush the fuel lines of old contaminated gasoline and water.After a thorough flushing,replace the fuel filter with new.Also,add a small can of "Dry Gas" to the fuel tank as this will take any remaining moisture out of the tank.Good luck.
