C4 Picasso HDI fuel line help???

[Mark079]

Hey all, 2017 Picasso hdi I have broken fuel connection somewhere behind the engine, I have removed the fuel filter housing and the connection I’m
Looking for is the pipe from the filter housing with the white push to release clip, it runs below the housing and connects to something plast that has snapped! I have located the end of the pipe with the broke plastic lug connected to but cannot find out where the plastic lug and connector has broke away from if any one could point me in the right direction I’d greatly appreciate it! I believe it’s a hdi blue as there is no priming pump and the fuel leaks when ignition is turned on but not cranked over! It’s drove me mad all day!!

Unfortunately your car is too new for the system diagrams I have access to. Hopefully another member will see your query and help out. Good luck

Ok so I managed to locate the part at the rear of the engine bolted below the fuel rail, fuel temp pressure switch is what it advertised on flea bay as! 55£ genuine Psa PITA to change but seems to have not been the problem as I still have (what I think is) diesel leaking from the rear the of the engine somewhere as soon as the ignition is turned on! I did have some error codes but didn’t take a pic at the time due to being in a rush! I will get it on lexia tomorrow but any help or ideas greatly welcome! From looking under the car the spillage seems to come off the subframe roughly in the middle or slightly to the drivers sides ! Quite a bit comes out too

Have you checked if the fuel filter drain is leaking ?
