A very interesting an informative video. It got me thinking. Aircraft have sumps in their fuel tanks designed to allow any water present to sink into them. Then a sump tool, basically a spigot adapter with a clear or translucent bottle on it, is used to drain off a small amount of the liquid in the sump until fuel comes through clear with no water contamination. I wonder if a similar idea would be useful in clearing contaminated fuel from an overlander's tank(s)? I imagine it might greatly speed the process of purifying water contamination way out in the bush somewhere.
Bill, this was an incredibly useful video! Thank you. I’m in the US and have a 200 TDI swapped Ex MOD 110. I will be incorporating this setup on my vehicle! I hope you’re enjoying the current trip.
Good man however I imagine that dodgy fuel in the US is pretty rare. If you install a CAV pattern prefilter you will find that it uses the same filter elements as the standard LR fuel filter. You should really use a coarser element for the prefilter but these are hard to find so I use just use standard filters in both.
This is brilliant. Everyone should do this mod to their vehicle. I have a twin in line fuel filter which acts a visual and then the main vehicle filter followed by a secondary finer water / sediment filter. Having the Racor marine sensor is great too. Dealing with the problem when it happens is simply a case of looking where the blockage or water is and draining the tank. Filtering it with a Mr Filter is new for me so something I will look into further. This is good practical advice. The last thing one needs is faulty injectors and or fuel pump. Thanks :-)
Draining the tank isn't so easy because of the volumes involved. However the contaminants will be sitting at the bottom of the main tank so if you draw off 10 - 20l into another container, filter it through a special funnel, put it back into the main tank and repeat the process a few times then you will get rid of the problem eventually. Several companies make filter funnels. Mr Funnel is just one such brand.
@@defendermodsandtravels Thank you. Usually it's just a case of taking out the drain plug in either of the duel tanks. I've done this before but from now on will invest in the Mr Funnel as well. We pick up tips as we travel. Cheers.
Thought provoking, could you fill your tanks through the funnel or is it too slow ? I've seen filter socks for motorbikes that are good for 17 microns.
I am hiking in Spain at the moment so I have no data available to me. From memory the prefilter is a CAV 296 pattern which is interchangeable with the standard LR fuel filter parts. The transparent bowl is a proprietary item, I forget where from. Remember to buy a nylon bowl, which is shatterproof, rather than glass. If you are fitting to an early Disco this is less important because the sedimenter is fitted inside the chassis rails rather than in the wheel arch. You will find Racor alarms at good ships' chandlers - I bought mine at ASAP Supplies in Beccles; UK They have different versions with visual and/or audible alarms. You will need an extra deep filter bowl to fit the sensor (I reused the bowl from the sedimenter) with a matching hollow retaining bolt. From memory I bought these from Darwen Diesels. I hope this helps.
@@defendermodsandtravels you are amazing - thank you for your prompt answers and yes I own a 1998 - first registered 2000 Discovery 300Tdi - from Amman, Jordan kind regards

Yes i thought the same. Have several jerry can to clean diesel.

Too slow I'm afraid. There are bigger ones which let the fuel through more quickly but they are too bulky to take on a trip.
Do you have a part/model number for the Racor water in fuel sensor and the filter which can be put on the LR water sedimenter? Thank you
