I would be wary about what mechanics say - I was getting fuel related fault codes and limp mode on my L series and all places I went too - diesel and LR specialists all said new pump and injectors.
I managed to get the actual number of the fault code (something the "specialists" should have done which pointed to a fault occurring on shut down which is what was happening - start the car from cold and it ran fine until shutdown and then on restart it would go into limp mode and check engine light on.
Rather than pay the $3500 to $4000 being asked I decided to look at it myself - the pump itself was a bit daunting so started with the easy stuff first - the fuel return lines from each injector had perished a little and were weeping fuel but not enough to cause the fault - so then looked at the fuel shut off valve - there was a little bit of crude stopping the valve from fully closing - enough to stop the engine but still letting enough fuel through to trigger a fault - took about 10 minutes to fix and no dollars - saved up to $4000.
So i appreciate you may have to rely on mechanic advice but always look for other options - like sending a PM to Woko on here - always helpful and knows these vehicles inside out. He was last online 4 days ago so is around.
As far as the leak is concerned - yes the pump might be leaking but look for the easy things first like the rubber fuel return lines - as said mine were leaking, I thought it was from the fuel pump. It is special stuff, small diameter and expensive ($25 a meter) and can be bought from any major diesel repair shop.
Give Woko a PM :-)
