Golf Mk5 - possible fuel leak

Afternoon all.
I hope everyone is enjoying the summery sunshine.
Being a kind hearted soul I shan't mention England’s lacklustre performance last night . . .

Anyway I was wondering if anyone on here has experience of working on the Mk5 golf.
Does anyone know if there’s a line carrying fuel on the Mk5 that runs near the rear wheels?
Mine seems to have a leak at the rear, just before the wheel.
The smell is a bit like petrol, but not sure if that's possibly caused by dirt/grease/etc. just polluting what I hope is water.
Just thought I'd throw this out there and see if anybody has some insight.
Ta.

Afternoon.
Well once I actually got to look at the car in person the problem was obvious, a leaking fuel filter.
So once that was replaced, it was all blocked up, the car was grand.
Makes me wonder why there isn't a warning lamp for fuel pressure and a programme that cuts the motor as it was possible to drive the car with fuel pi55ing out the back.
Anyway 'tis solved now.
