Rickl,
You beat me to the crunch. All the symptoms you mentioned were the same in my case and wouldn't rev beyond 3500k for me.
Changed out the fuel filter....wow the power was restored.....
Sorry couldn't get in earlier to help you with the problem.
I changed fuel filter at same time I changed out my faulty fuel pump.

Hi All
Well it was too good to be true. After a few days of running reasonably well the same problems are back. I have checked the new fuel filter and it looks fine. I actually had another new filter on the shelf and I tried fitting that but it made no difference this time.
I pulled the fuel pump out last night. I had this pump installed a little while ago when my pump just died and I was in a hurry to get the car going. I have no idea where the mechanic got this pump but I am a bit concerned about the way he has installed it.
For some reason he has replaced the factory fuel hose on the output of the pump. The hose he has used is a black rubber hose marked as safe for submersion in fuel. He has used a hose clamp on each end of the hose. The new hose is no where near as flexible as the factory hose and seems to be pushing the pump down.
Is it possible that the installation of the fuel pump could be causing my problems? Without a fuel pressure gauge is there a quick way to see if I am getting the fuel pressure and/or volume I should be getting?
Is it worth just biting the bullet and getting a new pump?

The hose should have no effect as long as it is the corect length. The OEM is very flexible to allow the pump to rise if the tank gets a clout. You will notice the whole assembly is on sprung columns.
The filter sock will have notches in the input to the pump.
Just check that the filter sock does not have any splits as this happened to me in NT. Some fluffy stuff went through the split and the car would go well for 15 minutes then take no accelerator. Stop and the whole process would repeat. It was that the fluffy stuff was blocking the inlet pipe of the pump, then would fall out as I stopped the engine.And so on ad infinitum.
I flushed the tank and finally as a last resort in Mataranka pulled out the luggage and changed the pump. Later looking at the pump I pulled out I saw the problem. AGGGGGGGH!

Hi All
At long last the dramas are finally over and the car is running fine again. The problem turned out to be the fuel pump. More correctly the dodgy mechanic who replaced the fuel pump a few months back when it failed one morning.
The guy had dropped the rubber fuel sender sealing ring inside the fuel tank and had used black silastic gasket to seal the sender unit to the fuel tank. he did this because without the rubber ring the lock nut could not tighten down far enough to hold the sender unit. To make things worse quite a bit of silastic was inside the tank.
When i pulled the pump out I noticed some black muck on the outside of the prefilter but thought it was just sediment in the tank. The tank was very low on fuel and i noticed some lumps of black stuff inside the tank. I soon discovered they were dissolved silastic.
I checked the new fuel filter I only installed a week or so ago and found it to be blocked. When I cut it open I found this black muck inside it. I flushed out the fuel line from the filter to the pump and there was a little muck in there. I spent a few hours cleaning the entire fuel system.
I decided that the muck must have gone through the pump to get to the filter so I installed a nice GOSS $75 VN Holden Commodore pump and put the whole thing back together. I put the rubber ring back where it was supposed to be.
Surprise the car runs just like it should. The poer is what I was used to before all the trouble started and the fuel economy (yeah right:cool:) is back to where it was.
The lesson I have learnt is to not trust a service station mechanic who tells you he has never touched a Land Rover before. It would have been much less of a hassle in the end to get the car towed to someone who knew a little about Land Rovers or basic workshop practice.
Thanks to everyone who offered idea and support while I was tearing my hair out.
Best Wishes
Rickl
AFAIK the syetem on Land Rovers is exactly the same as on Commodores and numerous other cars.
He was just a lazy ignorant robbing SOB who had no excuse for his action.

Great stuff silicone except for where petrol is involved.
