T350 fuel leak

[astonman]

Drew my 2005 T350 out of the garage,and after running for a while,there was a small puddle of petrol dripping down just inside the drivers side rear wheel area.
What do you guys think is the most likely cause?
It doesn't leak when the fuel pump is switched off, so I guess it's not the tank itself?
Thanks, Simon.

Fuel line runs on the top right hand side frame tube so might be a leaking pump connection and the petrol running along the line before dropping?

I wondered about that,the two rubbers pipes were replaced at 4 years old( they were cracked superficially).
They are located via the boot floor,if I remember?

Pipes from fuel tank maybe?

[astonman]

Hi, yes those are the 2 pipes that were replaced 13 or 14 years ago.I bet one has split, they are 8 mm ID if I remember?
I have some Gates fuel injection hose.
Thank you.
Simon.

Thank you,for the help,yes it was one of those two lines, can't tell which,but replacing them with Gates fuel injection hose has fixed the leak.

Excuse me being a numpty... I assume this is a view of the rear driver's side wheel arch, with the wheel removed? It looks like a fiddly job, but doable I guess. Useful to know these things.

That is correct, driver side rear wards in the wheel arch 👍

You access the two pipes,from under the boot floor and the offside rear wheel arch.
Snap open the quick release fasteners on the pipes from the wheel arch,there is a plastic pad or button to push.I had to push them with a largish plane screwdriver.
Then slacken the hose clips from under the boot floor and push the pipes off the fuel tank tubes.
You can now remove the rubber pipes and replace them on your work bench etc .The rubber pipe is nominally 8 mm, I used Gates fuel injection hose.

I found silicone grease was useful to lubricate the pipe for sliding into the fittings and to lubricate the push button snap fastenings.
When removing the hose from the plastic snap fastenings,you need to split the hose with a sharp blade,eg Stanley knife,but ideally you need to avoid cutting into the fastener,which has a rubber O ring on it which is easily damaged.

The snap fastenings are similar to the above
