I'm plumbing my fuel system at the moment. I can preserve the normal route - tank to sedimenter to lift pump to filter to engine. The sedimenter's mounted on the bulkhead next to the fuel filter, so a neater solution would be to flow from tank to lift pump to sedimenter to fuel filter to engine.

Will the lift pump care if it's upstream of the sedimenter? It could be running on some quite low-grade fuel, but I'm hoping the lift pump is robust enough that it won't matter. I do want the sedimenter to protect the injection pump and the injectors though.

Someone must know? Any horror stories of removing the sedimenter on an overlander and breaking the lift pump?

doesnt matter were you site it, doesnt matter if you remove they arent fitted to all landies and your filter has a drain bung to let any crap out which is seldom for most, a second filter fitted before the lift pump would be a better bet for you id think

200 tdis haven't got one or any of the previous engine types either.
I'd do as your suggesting or omit it all together.
Just my opinion.

I think they were fitted on older diesels that were intended for the export market, due to the very poor fuel quality that was found in some parts of the world.
They are something that I usually encounter on plant, boats, and machines that are intended to operate in a harsh environment.

They are actually a good extra bit of filtration, but with modern diesel in the UK being usually of good quality, they are a bit of an anachronism on landrovers.

Thankyou to you both - either solution would be better than multiple runs back and forth from engine to bulkhead. As it happens, both have the same bolting interface, so I could swap a filter for the sedimenter without any difficulty, I think.

You could, or you can get a twin element filter and do away with the other filter altogether.

I just read this today so you may have finished the job but I would definitely clean it and leave it in place , if it’s full of water and dirt and you find the same when you drain your filter you have a lot more water than you think . If part of the filter that contains the water etc fills up at the bottom of the filter any extra goes straight through to the fuel pump. Fuel may be clean when goes to the garage but they regularly check with paste on a dipstick for how much water ( condensation. ) is in the tank. Fuel to the pump is drawn from the bottom of the tank which is always where the water settles regardless of the quantity of fuel above it.

Thanks all - I've got the sedimenter mounted on the bulkhead now, but can't get fittings to suit it - they're not the same as the fuel filter banjos, which really surprised me

I do intend to plumb it in somehow though as I'd rather all that water ended up in the sedimenter rather than in the engine!
