It’s like when the leak off tube fails between the injectors,nothing shows but allows the air so to the system & drains back to the filter
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.
