    The fuel will float on top of the water and what they are trying to say is there is whats called a water fuel separator that is in line with the fuel line. This needs to be drained every so often, all this fancy SEPARATOR does is it creates a void in the fuel line so that any water in the fuel system will fall to the bottom and be trapped, since it is the denser liquid and the fuel continues on to the fuel delivery system. Hope this helps you!

    The specific gravity of water is 1 and the specific gravity of fuel oil is 0.864 +- so the lesser SG will be lighter and therefore 'float'

    Diesel will float on top of water (fresh or salt). there should be a drain at the base of a fuel tank to remove the water from the tank, and fuel will make water from the condensation because of the different properties and temperatures.

    Fuel filter units will also normally have a drain to remove water content

    Which is why your marine diesel engine will probably have a water trap somewhere in the fuel line that needs to be drained from time to time.

    it is not as undesirable as you are able to desire to think of, exceptionally considering the fact which you haven't any longer started out it yet. All you're able to do is get somebody to empty the gas tank and positioned clean diesel back into it. maximum diesel gas platforms have a water filter out alongside with particle filters--or a blend unit, to filter out the water and airborne dirt and dirt. Your engine might run for a whilst with water in the gas--finding on how plenty is in the tank, yet might at last the two run erratic or end altogether via water no longer being flamable. additionally some injection platforms use diesel gas as a lubricant and cooling medium for the injectors itself, so of course they might not be getting astounding lubrication with water. in case you probably did initiate the vehicle and run with water in the gas, injury to the injection equipment could desire to effect. do no longer situation, only drain the tank and positioned new clean diesel back in. luckily you found out the blunders of your tactics and did no longer initiate the engine. good success!

    Diesel is oil, so it floats on top of water.
