Fuel return line

[Kentm111]

Dead simple question.

The fuel return line on the i-cdti engine running from the fuel rail to the pump... should it have a clamp at each end? I am on about the one which is about 8mm diameter.

Only reason for asking is that mine hasnt and I am trying everything to find the recent contineous build of air in the fuel filtre... this I guess is a good likelyhood for my other post of Limp home mode


I would take a pic but my phone pics are too high of a res to post .

Thanks in advance for all help... as ever !!

Thought you meant the fuel return part 5.

I found the original filter had a faulty screw thread (and seal) in the drain plug that meant fuel went out and air got in.

But only after I had played with it /replaced it .......
