Re: Diesel Smoke
Water in the fuel would not be the cause of the smoke; nevertheless, it is a good idea to avoid having water in your fuel tank by keeping the tank full as much as possible.
Check your primary fuel filter - may have a plastic/glass bowl at the bottom with a spigot/valve. It is the first filter from the tank, likely on the wall in the engine compartment; the secondary fuel filter should be mounted on the engine. Drain away water, sediment and cloudiness until fuel is clear (dyed red, of course). You should be changing your primary and secondary fuel filters no less often than annually.
I had my diesel fuel polished and my tank cleaned by a professional. Clean fuel is particularly important for a diesel engine.
