No, the disco does not have a diesel burning heater. The sender unit is the aftermarket type like this one: http://www.paddockspares.com/prc7129-fuel-pump-and-sender-unit-diesel.html

Yes, completely certain. Could it be an earth?

Hi Sierra. Thanks for your answer. Yes the fuel gauge works. Do you know what the small wire is for?

Yes the bearmach lift pump requires a spacer. It was included in the kit.

Glad you asked :)

There is almost no fuel in the fuel filter. If you ask a fourth time I suspect there will still be almost no fuel in the fuel filter.

The pump is from Bearmach and the pipes are on the correct way around.

There was almost no fuel in the fuel filter when I checked it.

Yes, I put on a new fuel filter a few weeks (and zero miles) before I replaced the lift pump but I have not put on a new filter since I replaced the lift pump.

Sorry about that Magic. There was almost no fuel in the fuel filter when I checked it. My current prime suspect is the wiring at the top of the sender unit. A loose wire can't be good and I guess it might mean that the sender pump is not operating. Do you think this could be the culprit...

Hi all, I am investigating a low power problem on my Disco 200tdi and by elimination I suspect it might be something to do my unloved sender unit. I removed the cover on the boot floor to find that the small wire seems to have snapped off from the plastic plug that slips onto the metal lug (see...

Many thanks Magic and Paul. I have done the following: Cleaned out sedimenter Replaced diesel lift pump Cleaning out the sedimenter made the exhaust gasses much less black but neither of these has given my disco any more power. It still does not want to go past 1,500 revs. I have removed the...

Thanks Magic. I will check the level in the fuel filter tomorrow. Regarding the sedimenter should I replace the O rings on it when reassembling it?

Thank you Paul. That is very helpful. I want to check everything possible because at the very least I will learn a bit more :) I was not aware of either of those potential causes so will investigate them with vigour. I am also open to any suggestions from other members.

Hi all, I have a problem that is vexing me. My manual Disco 200tdi (92k miles) will only start on the second turn of the key and when I get to junctions it wants to stall. I can prevent this by quickly applying some gas in neutral. I have cleaned the air filter and replaced the following but...

Many thanks Flossie. Do you know if Bearmach ones are reliable (the price difference is huge)?

Hi, I am considering replacing all four glow plugs. As I am sure you know prices vary dramatically depending on if you go for budget, OEM or genuine. What brands and suppliers do you folks use?

The OP (not sure what it stands for but it seems to be referring to me) has now successfully troubleshot the problem. I did it by creating a kind of fuse-box Sudoku and analyzing every fuse and mapping them onto a diagram. I now have a list of over half the fuses and their application. The...

Thank you Brian, I was beginning to suspect it was an unusual fuse box. I am not sure how a multimeter would help me find the correct fuse. Please could you explain how I would go about that. Many thanks.

Thanks Dragonwalker. I have already tied swapping all the 20amp fuses in the fuse box for new ones. Do you have a diagram of what the fuses in the fusebox do so that I can identify which one is for the stereo?
