My number 1 leak off pipe was leaking and I never noticed for ages until I took the manifold off to do the glows.
The Landy Gods are smiling on you,best get it changed and check the rest.
Oh well..
No def leak off (or whatever folk call them) pipe as there's a bad puddle. Or if that's what you also call it them my mistake.

It is where excess fuel not used by the injectors goes back to the tank ready for another pass. For some reason #1 seems to go first but it is hidden under the inlet manifold and the FIP is in the way so it tends to pool in the well where the injector is and then dribble down behind the FIP, out of sight and out of mind. Finding decent pipe is a nightmare.

Number 1 is the only one with a well around it so that's the one that puddles.

Leak off pipe is separate to injector pipe. P38 diesel Is different to most systems as it has injectors but a mechanical pump not a pressure rail like same enginee on an L322.
If No1 is gone rest won’t be far behind. I notice reduced mpg normally then there’s bubbles in clear pipe when I check. Some stuff only lasts 6 months I try to get old stock. 2m @ <£10 is usual from a motor factors and will do the injectors, one to FIP and the MAP pipe.
The LR individual packs cost a fortune and aren’t much different don’t bother.

Putting Cable ties on the ends or heat shrinking the ends can help them to last longer.

Clear but yellow? Translucent yellow?
Sounds like it might be worth @tomcat59alan giving it a go. I think they water the fuel down in his area with something vicious.

You've just given mine the kiss of death. Have you got a link for the pipe @dubbleRR ?

That stainless steel braided pipe I bought was too big to fit the injectors so I took the braiding off and used the pipe, which, saying very quietly, hasn't leaked until I go out to check it tomorrow.

One lot I had was thicker stuff, only very slightly, didn’t want to go on the injector as pushed against the engine. Think I even tightened one a bit just to get clearance
