C250 Engine cutting out

[Jon jon]

I have had a problem with my S reg C250 cutting out while driving, all speeds towing and not towing, then not restarting. After about 2 hours or just when the recovery people are on their way hey presto it starts !!! Royal PITA !! Also had problems trying to start it from cold but not with it parked nose down. I have read the threada on air leaks in the fuel lines - is the cutting out part of the same problem?

Yup, almost certainly the clear pipe O rings, can you see air in the pipes or are they too opaque?
