Ok i didn't mind *too* much when it was keeping my old rotten chassis rails oiled up, but now I've got new shiny chassis rails on, I'm peed off that it's still dripping fuel. Especially as its so far been variously diagnosed as a split breather, a damaged fuel pump/sender unit seal, and a loose clip for one of the four hoses. Due to time being tight I've been throwing it at the local 'experts' and have paid handsomely for the privelige.

I've just got the bastard thing back from having its new 1/2 chassis fitted and it's still leaking - dripping off the bottom of the tank and the chassis rails... As the tank had to be dropped anyway I asked him to investifagate the leak. The diagnosis this time was a loose clip, which was supposedly pushed fully home this time.

It's coming from on top of the tank, in the vicinity of the fuel pump. Does anyone have any ideas?
 
The rubber seal around the neck of the aperture for the pump could be coming adrift. Mine did after I brimmed the tank one time. Check out www.discovery2.co.uk and search on here for info on accessing the in tank pump and correctly seating the seal. Also check the condition of the fuel pump locking ring.
If no joy with those it could be your fuel line connections on top of the pump (Edit- youve already mentioned these sorry) or possibly a line chafed through between the top of the tank and the body.
 
There used to be an issue with D2 fuel lines, can't remember exactly but hopefully might jog someone's memory, something about them chafing at a particular point where they are clipped to the chassis somewhere near the fuel tank.

I'm sure I've come across that as well, and seeing as the tanks been dropped it might've exacerbated something :(
 
Thanks for all the pointers. I *really* don't want to have this bastard tank out again...

Yes, yes it does. I read that with interest, thanks.

At the weekend I'll lift the carpet, open the access hatch, clean any diesel up and then fire up the engine to see if I can see where it's coming out from. I do have a spare pump 'in stock', but it's a non VDO one and I've been warned off putting it in...

Sounds like a plan ;)
If your pumps leaking it's got to be better, at least short term! Hopefully it's something daft like the locking rings tired or the seals dislodged :)
 
on mine it was the pipe with the green connector funny money from landrover who wanted to sell me the 4 pipes, found one on ebay from Fews around £40 quid easy enough job to change it, when you disconnect the pipe from the pump tie a piece of string to the old pipe and pull it out from underneath and use the string to pull it back into place, hope this helps

well I'm planning to have a look at it tomorrow, so hopefully all will soon become clear!

I've not messed around with the fuel system on the D2, so I'm in the dark a bit. Where does the green pipe go to (where is the other end)? And the other 3 pipes? I must admit that until I looked I kind of thought that there would be 2 pipes, a feed pipe and a return...
 
the pipe with the green connector is not very long it terminates at a push fit clip on the inside of the chassis leg the clips can sometimes be a pain to release due to some one at land rover I take it having it so tight to the chassis if you crawl under and look up at the drivers side chassis rail you will see it mine was leaking not that far from the pump when you put on the ignition it came pouring out
the other three pipes I'm sure go to the fuel filter

I think I've found the culprit. Three of the lines had very loose clips, the lines weren't tight into the pump and it looked as though the clips were badly worn. I cleaned up the diesel and then turned the engine on and there was a drip, drip, drip from the connection of the 'black clip' pipe.

I suspect that the o-ring on the black connection is shot and that the clips are all past their best.

I think I'll put my 'in stock' pump in with the new clips supplied (that hold the blanking plugs). Hopefully that'll sort it.

When the old pump is out, I'll replace the o-rings at my leisure and put that one 'in stock'.
 
Well, that *appears* to have fixed my problem. So much for paying specialists to do a job for you... I'm actually quite annoyed.
