Technical water getting in diesel filter
I was wondering about this the other day.
On my old Toyota Lucida, the filter bowl had a drain tap on it, and needed draining regularly.
Diesel is very Hygroscopic (readily absorbs water), so you're always going to have water present in the fuel.
Anyone know if the filter bowl has a drain on it?

Water getting in diesel filter
I'll have to check mine.
I'm sure I read/heard somewhere that modern (the Lucida engine dates back to late 80s) diesel engine fuel systems are designed to draw any water traces through before it builds up to a level where it would cause problems, could be mistaken though.
Maybe I'm thinking of Aircraft fuel tanks.
Kerosene (Jet fuel) is very similar to diesel, and we regularly have to check the water drains on the tanks of our Aircraft at work, even though they employ 'Jet-Pumps' (venturi pumps) to constantly draw any traces of water at the bottom of the tanks through the system.
Some relevant info here...

Do you know that there is definitely water in the fuel, or are you just taking the word of the dashboard warning light?
My warning light came on persistently a year or two back. It turned out that one of the connections can be a bit dodgy at times (can't remember which one), flagging a false positive. According to the Fiat/Alfa specialist that looked at it, a known problem. I'm sure I've seen some posts on here in the past about the same problem.

Water getting in diesel filter
Took my filter off yesterday.
Had to remove the fitting from it's mounting to get to the upper right engine steady during Alternator replacement, so I thought I may as well whip the filter off to check it.
I've been getting the 'DIES HUMIDITY FILTER' warning regularly recently, along with several others (just before the Alternator died), so it could be a false alarm.
The sensor in the bottom of the filter is simply a pair of contacts seperated vertically by a plastic spacer approx 12mm long.
If water builds up in the bottom of the casing, when it reaches the upper contact it makes the circuit for the warning.
