C4 Picasso 2014 Dv6C injector fuel run off pipe replacement tips

[Byngo9]

Hi guys, long story but I need to replace my injector fuel run off / return pipe ( got one from Citroen plus a set of little green o rings).
The connection point behind injector one near the cam sprocket looks awkward. How does the connection come apart to attach end of new pipe?
Looks like there's also a stiff plastic pipe over the top of this area ( see pics) that's in the way, think it goes to the throttle body.

Going from your picture I would take the thick pipe off altogether while you are replacing the run out pipes. IIRC you ease the green clip off with an appropriate tool and then just pull off the pipes and replace fitting new clips as you go. It is probably 10 years since I did that job so hopefully someone with more recent memory will be able to advise you better than I can.

Ok, yeah if it's the fitting with the green clip I need to disconnect at then that makes sense ( like the fuel lines to the fuel filter I guess).
That black pipe is rigid and looks like I need to unbolt the pipe assembly further towards the front of the car and undo all the jubilee clips holding all the pipes to it, then after undoing the jubilee clips at the throttle body end, it be be able to slide back towards me? ( Just trying not to fxck this up and break something) Lol.

Ok, did the job, spill off pipe replaced and new little o rings on the injectors. I did undo the clamps and bolts holding that intercooler pipework to get it out of my way, that went o.k.
Where the spill off pipe comes apart from that green clip I couldn't see an o ring, surely there must be. I will see how it goes for fixing my diesel leaks.
