Fuel sedimentor on a Td5?

On my 300 i've got the proper sedimentor fitted in line with the main filter, it does an admirable job of collecting muck and poo that i get in jerrycans etc.

Now i'm building a Td5, i fancy having the same thing.

I've got another sedimentor. but which fuel pipe should i plumb it into? the main Td5 filter (which looks suspiciously like a Tdi filter) has 4 pipes going into the filter "head" (the head looks identical to a Tdi one) whereas the Tdi just had 2... in and out.

anyone know if there is a proper Td5 sedimentor kit?

cheers

Don't think so - the Td5 fuel system operates under higher pressure/flow so I suspect a conventional "sedimentor" (which I think probably relies on relatively low rate of pressure/flow to allow the gunge to settle out) probably wouldn't work.

To be honest the biggest weakness in a Td5 run on low quality fuel is the pump - all that protects it is the strainer in the tank and when that gets bunged up the pump can end up working too hard and failing, a bit like a person does when you put a pillow over their face and sit on it.

Putting a sedimentor downstream of the pump wouldn't help much, because most of the gunge that the sedimentor would take out would already be taken out by the strainer on the pump (except water of course).

All IMHO but I don't think you would gain much even if you could figure out the plumbing.

Just been looking through microcat Ralph.

It shows the sedimentor for the Tdi's and earlier, but nothing mentioned for the Td5.

the part #'s you posted are for the main filter (the jobbie with the 4 pipes), it's the pre filter sedimentor i'm trying to fit.

maybe i might need to get some special pipes made up. :unsure:

and to add to the above....

the Tdi/Td5 filter is exactly the same physical fitting and interchangeable at the top end but the Td5 one has the water sensor which screws into the bottom which is connected to a helpful warning light which tells you the water sensor is broken (apparently on the odd occasion it also lets you know of water in fuel...)

Gotcha. and possibly the sedimentor (Which has relatively small fuel holes) might restrict the flow too, and cause the heart attack symptoms with the pump.

wonder what the extreme :rolleyes: G4 vehicles have? unless LR ship in "clean" western fuel.

I've just been looking at the fuel sensor thing. looks like it's an add on that screws to the filter.... the td5 tank and pipes i've just collected hasn't got the water in fuel sensor in it.

EPC calls it Sedimentors - Diesel - Td5 -- that's all I have to go on.

That answers a few questions Ralph... cheers for that!

a ) there isn't a separete sedimentor

b ) there seems to be a lot of filters in the bottom of the tank. shame they are where they are though... not exactly accesible.... <_<

'Old Ginge' at the Buck Emporium of expensive Land Rover Bits had a very nice way around this problem. He used a Tdi tank and an external Pacet pump. The fuel pump isn't that high a pressure at all (all the pressure is done in the wizzybangpop bit so he found you could use 'normal filters' his way...

Why not ring the jovial old chap and have a chat?

Not compared to injection pressure, but I think it is a lot higher than the Tdi fuel system which basically only needs to circulate fuel so probably only has a few psi in it, and its that pressure that the sedimentors are intended to work with.

Wizzybangpop bit, nice technical term there :)
