Fuel leak

[Menash]

Hi everyone,
My disco 2 td5 2004 start to leak fuel yesterday. It seems that is pretty serious one just above the tank. I will send a video (not so good, sorry).
Where do you think i should start looking?

If it’s directly from where top of fuel pump is, check the hoses going to fuel pump and make sure connection is good into the pump and if they’re ok then check each line for rub through. when do you see this leak, engine running or constant leak? happens driving around or standing still?

It's probably the green fuel pipe which rubs against the wiring loom for the pump. Known TD5 issue so that's where I'd look first.

The replacement line is available on its own (YNI500030K), it's easy to replace and doesn't need the tank dropping like the LR instructions say.

I checked the pump today and it looks dry. I red that the green one is usually the problematic and i wonder if ishould disconect it from the pump and pull it from the bottom of the car. Would u suggest to replace all of them?

Thank u
Do you have a link for a short video that demonstrate it?

Can’t find a video but green goes to the FPR in the engine bay, the pipe connects from fuel pump to the main length of fuel line that runs along the chassis, connector is on top of chassis between fuel filter and body mount if I remember correctly. I think it’s the inner line not the outer one.

you’re after the top one, connects to main fuel line to FPR, use that to gauge the connector location.

No but you just need to disconnect it from the pump, remove it from the clips across the top of the crossmember by the tank, then pull it through from underneath. The other end of it is by the body mount on the chassis.
It's rigid enough to then push the new one back through towards the pump, although you can make it easier by taping some string or wire to the end of the old one before pulling it out and then use that to pull the new one back in.

Thank u all
I will order the part first and then deal with it. I will order the green one and hope the statistic will be at my side
