Citroen DS5 fuel filter housing connection mesure

Unread post by onnik »

Hi, yesterday while I was changing the timing belt I broke the fitting that goes into the fuel filter after the pump,

Does anyone know what size the fitting that goes into the filter cover is?

I found it on Amazon but there are 3 different sizes
9,89mm - 8mm
9,49mm - 8mm
7,89mm - 8mm
Тhanks in advance, because I don't know how long it will last like this

If you match the part number on the top of yours to the amazon ones you should be able to get the right one. I can see the number in your picture but cannot read it there. :)

And so the problem is solved, the size is this 9.89mm.
bought this from Amazon " X AUTOHAUX 9.89mm SAE to 10.5mm 90 Degree Fuel Line Hose Quick Release Connector Disconnect Hose Nylon 2 Set "
I used the straight one, but maybe I can change it to a 90degrees one for a more neat look, I already know the size, The hose I got is flexible and will take the bend, otherwise it turned out like this

The silicone there now holds the zip tie pushed in there until these come.
