How to drain a gas tank

drop tank-----or if car runs and not much gas in tank add some high octane and a gas cleaner additive

no year, huh? some years have a check valve , there,....
this forum is for usa cars, is car USA car?
the tanks just dont like siphoning. (check valve)
the FSM covers this , in the fuel section under bad pump.
1998 to 2006, ill guess, 06

i have the FSM and does not cover. bad fuel, no drain plug.

it shows how to get fuel lower, in filler neck
the tank has check valve at it its metal neck.
so inserting a hose in filler, will hit this check valve.
and all you get out , is 1/2 fuel.
id use the tank out procedure.
then empty all fuel, after step 5.
quote:

1. Disconnect the negative battery cable.
2. Relieve fuel pressure in fuel feed line.
3. Due to absence of fuel tank drain plug, drain fuel tank by pumping fuel out through fuel tank filler.
4. Use hand operated pump device to drain fuel tank.
5. Remove fuel tank.

tip tank to drain the remainder. out

here is one more way. (IDEA!)
do 1-4
then tip car to left. Jacks then stands at frame.
then remove the filler hose on tank
remove that pesky check valve. from neck last.

and pump out the rest.

Or bad float !!

changing the filter wont get rid of the bad gas ---need to drain tank of bad gas and also re-replace the fuel filter also check the plugs not damaged or plugged

This is a Saturn ion i do not think there is and i would not even start this car if you even think there may be sugar in the tank,Water can cause a little damage but not really as long as there is gas mixed but still do not run engine. sugar is bad!!. this will cause lots of damage. converter, injectors and cylinder wall damage.
You will need to drop tank and drain it out and then flush it out good. then drain fuel lines and replace the fuel filter. after you are done i would put in a bottle of dry gas and a fuel injector cleaner additive in the tank.
Note ' make sure to flush tank good, When fuel lines are removed the fuel in lines should drain back out of lines. the only problem is what is in the fuel rail and injectors, this is why i said to add injector cleaner and dry gas additive to help if there is any small amount of water left in tank. hope this helps ,good luck.

Check your spark plug wires first. Then check your spark plugs. Either one of your wires is no good and needs to be replaced or else a spark plug is bad and needs to be replaced. The only other thing I can think of is bad gas. If you are close to empty in your tank, go and buy some fuel injector cleaner from the gas station. You pour it in when close to empty and run it until empty then refill the tank with gas. If its a clogged fuel filter or bad gas the additive will take care of the problem. If it still back fires and vibrates then its time to check the spark plugs one by one until you find the wire or the plug that is bad. Then replace it. That should solve your problem.

The problem lies in the sending unit in the tank. It could have a wiring problem or the sending unit is bad.

Several months could be a tank of bad gas. When turning the ignition to on position the pump runs for 3 to 5 seconds to pressurize the system, next find the valve on fuel rail and press it, Shield with a rag while doing this. You should get fuel. Check the way it smells, bad gas has an awful smell that can make you hurl! Attach a fuel pressure tester, it should be around 50lbs. If it's bad empty the tank by pressing the needle and relieving the pressure. Next disconnect fuel line before the filter get a container to catch the gas. IN the engine conpartment disconnect the fuel pump relay and put a jumper wire to run the pump until tank is drained. Instal new filter and pump if needed and add a can of "Seafoam" to the tank with fresh gas. Run pump until there's fuel at the fuel rail then put relay back in. now we should have ignition and constant running. Hope this helped.

You don't. There is no drain plug. If you are pulling it out to replace a fuel pump you just drop it with the fuel in it.

If you have to empty the tank you have to **** the gas out. Best to pick up a cheap hose that has a siphon built in it. make sure the tank you are putting the gas into is below the tank on the car. Start the fuel flowing and let gravity take over.

Hope this helps

most gas tanks don't have a drain plug.can eith try siphoning it out with a hose called a magic siphoning hose or disconnect the fuel line and put the line in a container to catch the bad gas.

other option is to drop the fuel tank and empty
