Thread: Diesel Fuel

Are people filling their Discos main tank with the funnel device? Because many Discos have the petrol connection preventative device ... I suspect that if a different sized filler is put into the fuel tank filler, then the Land Rover device might actuate ???

With my Prado D4D 150, there was a brochure from a third party supplier, who supplies to Toyota the water separator for the diesel fuel lines. The instructions were on how the device works, and also how to handle a fuel warning i.e. how to clean the filter when you get a warning.

But the Disco doesn't seem to have such a third party diesel water (and solids) filter ... at least, there was no separate brochure or booklet describing how important clean fuel really is.

- Does the disco have a decent bad fuel filter?
- Can you fit a third party one and who should do it for a still under warranty Disco?

Thanks

What a load of bollocks.

Mr Filter funnels are a waste of time, Your D2 has one of the best filters and water separators already built in, right there in front of your back wheel.

where do you store your funnel when its not in use, in a hermetically sealed compartment ?? what about all the dust and crap that collects inside its spout while its not in use.

How often do you crack the tap on your factory filter / water separator and drain the water out - never , yet you stuff around with a stupid funnel at the bowser.

And not filling up whilst a tanker is dumping its load - what a crock .
Any **** that gets stirred up in the tank will never get past your factory filter.

And to follow up on the last post,i have filled from heaps of JC's,do it all the time,never had an issue.

Two things though,i have the fuel filter changed in the D4 EVERY service.
Secondly i often don't use the last few mLs of diesel in the Jerry,as sometimes i can see small things floating in it.

I also try to fill up at the larger servos.

I haven't got a that filter, but it sounds a good idea to me.

As far as filling up with a tanker filling the tasks - on the channel 31 4WD show, they demonstrated how particles and water hang around in suspension, simulating a tanker fill issue.

In the aeronautical industry, where they use Avgas, and low moisture high octane petroleum, they are restricted from filling for 24 hours after a tank is re-filled. And planes have filters in their fuel systems.

Unfortunately there are too many stories to ignore such issues. With Japanese 4WDs, people put in a 3rd party filter, for protection. I am not sure how many Discovery diesel drivers do that, or how much it might cost, and where one would install it in a Disco.

I think some people are worrying too much about particulates and water getting through their fuel systems. It's unlikely that either would get through the particulate/coalescer filters in the servo to each bowser. Then you have a good filter/separator in your car already. They have a water sensor to let you know when there is excessive moisture buildup. If it comes on, stop and drain it out of the filter. Drain a bit off every day if you are worried about it. You would have to have a lot of water in the filter for it to get past the separator. Best practice is to try to keep your tank as near to full as you can, especially over night to minimise condensation buildup. IMO, the biggest issues with contamination occur from Jerry can filling.

isnt a 30 micron filter big?
I use a 2 for my oil,,

Good way to increase your oil pressure, running a 2 micron oil filter. Overkill if you ask me. Anyway, I think the factory fuel filter would be at least 5 micron, may even be 2 micron, which is about as good as you could get.
A rain drop is about 700 microns. Mist can go down to about 6 microns size. If you can see a particulate, it's bigger than 6 microns.
