Why do Diesels need a water separator?
Diesel fuel can easily become contaminated by water because diesel fuel absorbs water more than gasoline does. For this reason, many diesel vehicles feature a gadget called a water separator that collects water from the fuel. If the fuel contains a lot of water, you may want to consider buying fuel elsewhere.
How does a water fuel separator work?

Does a fuel filter remove water?
Some filters, especially found on diesel engines, are of a bowl-like design which collect water in the bottom (as water is more dense than diesel). The water can then be drained off by opening a valve in the bottom of the bowl and letting it run out, until the bowl contains only diesel.
