D4 Fuel water trap

[DRD]

I have been told that the modern vehicle need a dedicated water trap in the fuel line as water ingression causes major problems.
I need some ideas to where it could be fitted or if the D4 filter trap is good enough.

The problem with the D4 one (and later D3s) is its location, as its not a simple task to empty. Mine will get one mounted in the engine bay.

Where is it located please on the D4.

Its underneath the vehicle below the driver's seat with a cover over it.

I would add a comment that unless you are using your own sub standard fuel storage most of the fuel in Aus seems to be OK. I have a friend who has been running a dedicated water trap and alarm on his 100 series for 2 years and has yet to collect a meaningful amount of water. I was really concerned about the chance of contaminated fuel when I got the Disco 3 and am careful to avoid free diesel from on farm bowsers and low use bush service stations who do not get much traffic. Note that this dosen't include places like Jervois or Mt Dare who would quickly lose lots of business if they had common rail diesels being rescued 40 KM down the track.

One solution that I have considered is to mount a good water trap filter between my aux tank and the transfer pump so that I could use the second tank as a buffer to protect the main fuel system but I havent had the need to as yet.

Why they put that fuel filter where it is "protected" by the cross member so you cannot get at it is beyond me - they could have mounted it in the space just forward of the cross member and all would have been good. The water collection space at the bottom of the standard fuel filter is really not a catchment but simply the sensor.

A member of the LR Club ACT has had major fuel contamination from a local garage a couple of times and his Water Watch has saved his engine. A water watch would probably fit in the above mentioned hole or I guess up in the engine bay but ideally should before the car's fuel filter.

Thanks Graeme, I had been looking for it but couldn't find it. Then again I spent two days looking for the dip stick just after I got the D4...that's probably why they supply a manual with the vehicle, to be read, sometimes.

As Graeme suggested it needs to be accessed easly! I would also think that you could parrel the alarm sensor with the existing which would save putting an extra light/alarm in the cabin. As I under stand the auxilary fuel tank has a common filler so there is a risk of putting fuel directly into the main tank which would defeat the inclusion of a trap between aux and main unless you included a trap between the main and the existing filter/sensor, bit of an over kill.
One of the guys I know fitted a water trap with a filter which caused an engine fault alarm so the filter was removed and all is OK, must have restricted the fuel flow enough to trip a sensor.
