    As above. My lovely merc coughed and spluttered to a standstill this morning. I noticed that there is a lot of air flowing through the clear plastic pipes next to the fuel filter. I'm pretty sure this is what's causing the problem but I'm not too sure how to bleed the air out. Any ideas?

    Would filling the tank whilst having the car running have caused the problem with trapped air?

    I am not 100% sure, but I thought they were self bleeding. The problem I think you have has been written at length on here, you probably need to replace all the plastic pipes as the seals have probably failed, a common problem with E300 turbo diesels, have a look under the engine section.

    You may have a pipe or two leaking air in. Best to replace all of them or the seals on the pipes.

    it is self priming.

    You are best replacing all the clear pipes and o-rings (dont forget pre-filter oring)

    Thanks for the help.
    It looks like I'll be replacing the clear fuel lines then!!
    Is it all the clear lines I can see in and around the filters?
