A while back whilst driving home the Range Rover started to lose power whilst under load, especially hills.
Upon investigation the fuel pipe from the tank to the filter was corroded and started to leak just before the filter. As this section of pipe is no longer available in the uk I replaced it with rubber flexible pipe and replaced the filter.
Went for a short test drive an all ok.
Next day went out and straight away no power when depressing the throttle, checked fuel line, no leaks.
Could the new filter have got blocked up?
I have not yet removed the pump to check that, idles ok by the way.
Whilst checking the fuel pipe connections at the tank I noticed when I removed the fuel return pipe it was dry, when I removed the tank to filter pipe it was wet.

Any help appreciated

Thanks in advance

back to drawing board and establish a baseline, what is your fuel pressure? how is your primary and secondary ignition systems? do not forget timing and proper advance.
if all is in good working condition, then look into exhaust restriction due to internal rotted muffler(s) and or obstructed catalytic converters.
are the brakes dragging?, what is the operational condition of transmission?

yup... check fuel pressure & regulator. Also, check your air intake hose. The original ones can collapse on the inside when under load. Might as well check air filter too.

when vehicle is stationary and in neutral, if accelerator pressed to the floor only manages 3000 rpm, seems fuel starvation, does system need bleeding?

limited to 3k rpm, huh. I would check air intake as well, sometimes the intake hose collapses during acceleration thus starving the engine.
check same hose for possible leak.

I had a similar issue a while back. Check the ignition module. Mine was topping out at anywhere between 3-4k. Did realize that was the problem till it gave out completely.
