Ian also found a design glitch with the fuel filter but land rover were not interested in it.

I can't remember exactly now but it was to do with the unscrewing of the drain plug which meant that debris could actually be screwed back into the filter housing...we worked it out after find sand and grit in the bottom of a drain off checking for water and could not understand how it got there..after cutting open a filter it was obvious how it got there

A trick I learnt a few years ago filling aircraft in remote areas - place a small piece of timber under the 44gallon drum so it's on an angle.

Water will naturally flow to the lowest point of the fuel (heavier than fuel) so it gives you a bigger safety margin over contamination (you're not drawing from the very bottom of the drum).

Maybe one of these would be a useful addition to the list of things to take to remote places:

^^ there is a concern about fueling to or from portable containers,, mainly due to static electricity.
the idea is great!

a shammie (spelling), use it as a filter, water will not pass though but fuel will

yeppa thats the one, as long as its a real one.

we used them when toping of on back block strips, filling from 44 gallon drums

very fine metal gauze will do the same as long as it is wet with diesel before the water gets to it . The water will stay on top of the gauze while the diesel will go through. Also there has to be enough room for the diesel to push the water aside. If there's so much water on the gauze that it forms a complete layer, there could be issues of the diesel pushing the water down and through. Hope all this make sense. Don.

My understanding is that the fuel filter is 5 microns to remove water. I doubt very much that the filter filters mentioned above go that far so some water above 5 microns will get through which means that water will accumulate in the fuel filter and regular maintenance (draining) will still be required.

I have attached the relevant file from the Puma manual about the fuel system.

No 5micron is also to remove particulates. A water trap is still recommended.
