Fuel Leak...Hoses?

[richarde]

Have a td5 discovery. Leaking fuel at the top (RHS) of the tank. The mechanic reckons it could be chaffed fuel lines on top of the tank. Sounds like a lot of labour to get there so I thought I'd have a go myself. Has anybody here done this job??? Should I order special LR parts or will I find standard fuel hose etc

A pain to get at but yes can be operator replaced. The genuine hose/s all come together in a clipped arangement, you can just replace the chaffed one which is usually the one supplying high pressure to the fuel pressure reg, but I have noticed the newer ones have a slightly different shape/ routing probably to reduce the incidence of this happening, so maybe best to replace the set as they come.

Also, I would recommend paying close attentioin to where they run when refitting, you may want to leave the outermost chassis clip unused, as this one seems to add to the closeness of the pipes to the chassis. Perhaps some of an old rad hose wrapped around them will also help.

There was a recall on disco2 for fuel line rubbing. ring Land rover and see if yours was done

Correct about the recall, but I have redone them again after they were 'recalled' so even that isn't a guarantee they are fitted properly:mad:

Hi All. Don't wish to hijack this thread, but, coincidence that 'today' I am leaking (lots) of diesel from top right area of fuel tank. Diesel is only being pushed out whilst engine (pump) running. In the last few months I remember seeing a diagram on this site of the fuel tank and all its components. 'Search' has been frustrating and I cannot find the link to a previous posting. Does anyone recall the 'posting' for that diagram in previous months ?
Vehicle is 2003 TD5.
Many thanks.

JC,can you check these hoses from looking from under the vehicle,or do you have to look ontop of the tank,that you can't see from underneath,if you know what i mean.
To put it another way,do they rub through where you can see from under the car,or is it on top of the tank that they rub through.
Just thinking of preventative maintenence for mine .I can see the chassis clip you are talking about,i have put some of that grey electrical hose(not corro) around it.

Wanna check mine before they leak,as it is a pretty common problem.


Hope this will help others as well

I ran into a guy in the Simpson Desert that had his D2 fixed twice for this problem under warranty by the dealers.He was from Taswania:angel:

Yes you can see the errant hose, it is the one that connects to a push loc fitting on the inside of the RH chassis rail where it meets the rear upper crossmember in front of the fuel tank. It generally rubs through where it breaks away from the others and heads toward the front of the vehicle, as the last clip can hold it down hard against the chassis rail etc and rubs through there.

And yes, usually only leaks when engine is running, unless it is really damaged then it'll keep dripping after shut down. But the leak will be similar to the Exxon Valdes by that point!!!:o

This has been a fairly common problem in series 2 disco's and has occured on mine at 100,000km. As JC says, Landrover have recently modified the part (as of late 2009) to eliminate the problem. The part costs about $140 if you can't get the job done under warranty or recall.

If anyone intends to travel long distances or in remote areas I would highly recommend having these fuel lines replaced with the latest part as it is on rough roads that the rubbing of the hoses is likely to increase.

The repairs to mine were done by a Landrover dealership and involved removing the fuel tank. I think it is also necessary to remove the rear carpet.

I have just had my lines replaced for second time, in addition to the recall. This time I enclosed the new lines with rubber fuel hose which was split, placed over the fuel lines and wound with duct tape. Used extra cable ties to hold down in addition to the standard clips which have a tendency to break after a while.

Thanks to everyone for their input. Removed towbar and fuel tank today. Yes the faulty line was the one that runs to the front of the vehicle. It appears that the electrical loom that runs to the fuel filter has rubbed through the line (green connector at the fuel tank). I'll make some calls on Monday and check out repair options eg the new part Mundys talking about. Anyway we'll see how we go.
Thanks

Picked up the part (4 fuel lines in a "loom") $195.00. Completed the repairs on Sunday. Thanks to Clean TD5 for sending me a link detailing the repair. By the time I read his message I'd finished the job.

Anyway the fuel leak is repaired. Found some wear on the figure 8 fuel line going to the engine, caused by rubbing against rear suspension bolts.
I protected the line with a split hose and cable tied away from the bolts.

Now that this has been completed it's onto the next problem. I'll start a new thread for it though.

hey all,
just got home from work tonight realised i could smell diesel, looked underneath the car sure enough fuel leaking from hoses on the tank.tried to start the car to see if leak increased when fuel pump was starting but car wont start almost like a faulty starter noise(tick tick tick). was just wondering if this is normal with this issue if so apart from changing the hoses whats my next step re getting the car to kick over.(ive waited an hour or so and the leaking has slowed but carwont start still but almost kicked over???):angrylock:
