Ford Fiesta MK6 Zetec S 1.6 TDCI - MK6 1.6 TDCI Zetec S Diesel Leak - Matts97

Hi, I have a very bad diesel leak from 1.6 zetec s, I've changed injector seals etc but it's definetely not leaking from there. I had my friend who's a mechanic look, and he got a picture of where he thinks it's coming from, somewhere around the fuel pump.
Before he had a look, I replaced one of the pipes/clips because I thought that was the source of the leak, after replacement it's clearly not leaking from there.

I've attached an image of where my friend thinks the leak is, any help would really be appreciated, it's probably one of the most annoying problems I've came accross on cars.
