you say that its leaking a bit but what is it like with a bit of throttle is it then throwing it out.remember these pumps work at some pressure so if you cure the leak your mpg should return.if the landy is stressing you i find it better to leave it for a day then go back with a clear head and start with the basic's in this case its best to start with your fuel leak because either way you have got to fix the leak

Hi i have similar problem car still under warranty just got to sit back and let the dealer slowly work through it. however i have spoken to a guy named Gary at TD5alive, based in cleethorpes Have spoken to him regarding my problem fuel surging / engine miss fire ,I also am using a lot fuel.If I dont get sorted in the next 10 days Im going to get him to check it over £40 a hour but he specialises in the TD5 engine. Apparently has More diagnostic equipment for the TD5 then landrover Dealers.Sounds as if he know is stuff.
You can always ring him if you are to far away to drop your car in for him to look at,people will travel quite a distance to get his advise etc..look on website WWW.td5alive.co.uk
hope this helps.

Hi All
I am having a similar problem to ultra150, in that my disco starts to exibit a missfire between certain revs.
When I start my disco all is well for about 15 to 20 minutes, when the engine gets up to temperature. It is like someone flicking a switch and at that point the engien starts to judder like a missfire. This happens up to about 2500 rpm then seems to get better, but then I change gear and it judders til I get past 2500. Also a distinct lack of power. It has just been pressure tested and checked (not at a landy dealer nor been on the computer), injector cleaner put in and wow it goes like a bomb, but as I say when up to temp, judder and almost a limp home mode. I might try ratty's suggestion:

Tonyone- Your problem sounds like the injector harness has oil in it, remove the the plug under the rocker cover and see if there's oil round the pins a new one will cost about 50 quid.
ultra 150- I was reading Landrover owner and in the back pages there was some one with the same trouble your having I know you can't smell diesel in the oil but have you checked/changed the injector seals and copper washers.

if you have found that the fuel pressure regulator is leaking ,this will have a large effect on your performance and general running of the engine as the pressure for your injectors to work correctly should be 4 bar constant. with the fuel regulator leaking you will be encountering surge ,What i mean by this is injectors will start firing normally ,but then the fuel pressure will not be adequate and the injectors will try and balance themselves to counter react the loss of fuel pressure.replacing the regulator you will probally find your fuel consumption will be a lot better.
My car is suffering the same problem as it missfiring had new fuel pump fitted it did make a difference but not cured it.today the engineer returned and fitted a new fuel filter (rear offside wheel).running fine since it has been fitted but will more over the next couple of days only seems to give the problem in a morning.
hope regulator sorts it out for you

hi yes thanks every one for your help it is the regulator that is at fault . how i knew the injector seals had gone was by inspecting the old fuel pump it was stained black from exhaust gasses geting in the fuel return through the injectors''' as for the miss its the air in the fuel system passing through injectors making it missfire....
