How to drain gas tank - 1991 Cadillac Eldorado

no gas tanks are sealed, to drain you need a pump and take the float chamber out and drain with pump, then remove the tank, and pour out the tank nozzle to get the last drops out.

There is no drain plug on the gas tank. remove the filler tube and put a hose into the tank to drain it

There is not a drain for the gas tank in your vehicle. Very few if any fuel tanks have a drain in them.

should have flap door where you put gas nozzle into filler tube to fill up gas tank.if flap door not missing not too much got in gas tank.add more gas and gas treatment to remove water if you have stalling problems drain fuel tank.change fuel filter.

Unless there is a drain plug for the tank, my guess would be to use a syphon pump like you would use for a boat.

no have to drop the tank its hard to

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

ok..

• remove the negative battery terminal
• open the gas lid and remove the tank cover.
• under the car , under the gas tank is a drain valve , Its like a bolt)
• connect a running hose and let water flow under the car, (optional)
• get a large flat container
• remove the drain valve from the tank and let the gas run out into the container. when its almost full cover back the valve, empty the container in a gas container an then continue to drain.

easier method but most people say its unsafe,

you need a hose and a gas container,

1. pop the hood,
   
2. locate the gas filter
3. remove the hose leading to the gas filter, put it in your hose and place the other end in the gas container (ITS LIKE YOUR extending the hose to your gas container instead of the filter.
4. turn on the ignition and watch the gas pump out the tank to your container, (pump must be working for this to work)
   

Some fuel tanks have a drain **** that will allow you to drain all of the gas neatly. If you have a drain ****, it will be located at the lowest point on the tank. Loosen the valve and allow the gas to completely drain.
If your tank has no drain ****, you'll have to drain it by removing one of the fuel lines. The rubber hose that exits the tank at its lowest point will drain the tank fully. It will either be connected to an electric fuel pump, fuel filter, or to a hard fuel line that goes to the front of the car. Loosen the clamp on the end of the line that connects to the gas tank. Pull the hose off and allow the gas to run out of the tank into your container until it is drained completely.
