    You could try siphoning the water out (doubt you will get much out) and diluting the rest in a full tank of fuel.
    Really the only way to get it all out is to drop the tank, and let it run out, should make it easier being fairly light with only 4 ltrs in the tank.

    you will need to get it out of the fuel lines too
    also water in combustion chamber = VERY bad

    im sorry im not able to describe the process. just any form of water in the combustion chamber is bad. it can be picked up from the tank, pump, lines, injectors

    I dont think the water isnt going to do a whole lot, just drain the most you can. Then it might be an idea to remove the fuel hose at the fuel pressure regulator and hardwire the pump, to suck the remaining left in tank and lines. Whack a decent amout of fuel back in the tank. Worse that could happen it it will cough and splutter for a bit.

    EDIT: It also might be worthwhile putting some metho in your tank before you refill it with fuel. It should absorb the remaining water.

    water in combustion chamber is bad because water cannot be compressed or combusted

    Thats true but i dont think nearly enough has enterered the motor, too cause hydraulic lock or anything. As the fuel pump only primes when turned to ignition, and doesnt start up until theres oil pressure. Just take the spark plugs out and crank it over a few times should remove anything left.

    drain the fuel tank for a start, im not sure how much the fuel filter will catch try to blow out as much as possible from the fuel lines then put some metho in the tank (it will absorb the water) prolly 5 lts will surfice and then dump it out again.Or as previously mentioned take it to a mechanic.

    1, drop and drain the tank,
    2, remove the fuel pressure regulator off the fuel rail, (bulby looking thing with a vacuum hose attached to the plenum chamber on the passengers side of the engine)
    3, remove the fuel filter
    4,, grab an air gun, or a pressure pack of oxygen and blast it back through the fuel rail until no more liquid comes out the pipe near the fuel filter, may have to seal off the with a rag aswell the get pressure behind it,
    5, refit the pressure regulator,
    6, replace the fuel filter with a new one,
    7, refit the tank, fill it with petrol and add 1 cup of metho (mixes any traces of water with the fuel)

    you wont have to pull the plugs and crank as there would be very little water in there (will blow out the exhaust) the only problem i could see is that if a little bit of water is in the cylinder it could start to make a little surface rust so best to get it running as soon as you can

    We have a workshop in Lithgow and would like to help......
    We have often seen that people are at a loss when they encounter water in their fuel and it can be quickly eliminated with the use of the Australian Fuel System Additive called INTERJECT; Depending on how much is in the tank, you could hot wire the fuel pump and as water is heavier than fuel and sits on the bottom, it will be evacuated first. Use glass jars as a means of determining when the petrol colour comes through, and then just add 1 or 2 (green) bottles of Interject and you will have no problems guarranteed. Each 250ml bottle of Interject will completely encapsulate 250 mls of petrol and will be burnt in the combustion chamber.
    Once the Interject has "absorbed" the water, it won't seperate back out again, so it is rendered harmless to the fuel injection system.
    For those that are interested, we have a web site Blue Mountains Fuel Injection | FuelMate, Inter-Ject, Dyno Dynamics | Katoomba NSW which explains a lot more about how the Interject works.
    It's often good when the complicated problems are overcome so easily.
    Best wishes and happy motoring from an old mechanic that still loves to fix problems and look after people. signed Harry Holzmann.

    At the risk of perpetuating spam, there's no need to add anything to a petrol fuel tank to remove water. Simply run a tank or a few tanks of E10 through. The EtOH in the E10 will dissolve any water and it will be drawn through and remove with the fuel. If there's more water than can be dealt with by using E10 the car won't run well enough (or at all) to avoid removing and draining the tank anyway.

    In case u do it again...
    fuel (oil) floats on water so ur pump is going to suck up water and bugger it.
    You need to remove the tank and empty it completely. Syphoning will not get it all out.
