When that happened to me it peed diesel out standing with the engine running at an autoroute tollbooth! The airflow flung it all over the underside, inside the handbrake drum and over the rear door! Easy repair though.

Hi,
I've been trying to find the cause of my poor starting for a long while. I didn't even know the Discovery has a sedimenter. I just checked and it's still there. I have now narrowed down the issue to it either air being sucked in at the leak off pipes, or at the sedimenter.
My question is, to by-pass the sedimenter off, should I run new lines from the tank to the fuel filter housing, or is it possible to to simply join the existing lines at the sedimenter?
Sorry if I'm hijacking the thread.

you can just join the pipes from the sedimenter. These normally leak(let air in)on the top.
I would change the leak off pipes before doing the above. It’s an easy job

Thanks, I think I'll do both regardless.
I've been looking on the web for leak off pipes and although I seem to remember seeing silicone ones somewhere at some point, they are nowhere to be found. Does somebody know about this or is it a fabricated memory?
If you will excuse my ignorance, as it's not a nice place to hangout in this weather under the car - will the pipes at sedimenter simply join together or is there some adapter I should purchase before messing about with spanners?

Last lot I bought were just straight tube to be cut to length from Norauto in France. They came with blanking pipes too. So a very mainstream auto parts shop. They may well have not been silicon though.

Right another update - not a good one.
So spent the day on the disco again today, to start with i re-tried the gravity fed line and had alot of stalling issues this time round, no air at all in the system. So it may of just been a fluke that it previously ran nicely!
So i spat my dummy out and removed ALL injectors, soaked and cleaned them (they where pretty dirty but cleaned up fairly well), removed pipework that goes from pump to injecters soaked and blew out with airline (all cleared and clean so no issues there)
Put it all back together, bled the system still using the gravity feed, fired up, ran lumpy for 10-15 seconds, cleared up ran quite nicely, little to no smoke, ran itself at about 4-500rpm (i know its not ideal but better than it has been) for a good 3/4minutes then died and then doing the same as before.
I have ordered a new lift pump and a "boost pin" as these are cheap parts to replace. Before i go to the route of new injectors.
So i guess my question is, am i doing the right thing here? Am i missing something? Im really hoping the pump isnt knackered due to the price of them.
