Not had to post on here for a long time but now need some advice for my father.
We have a 1998 W202 C250 TD sport automatic. it's been fine for a while but recently after a 20+ minute drive it starts to run a bit rough and we can see air in the fuel pipe in the pipe that goes between the lift pump and the pre filter.
We haven't really done much to the car in terms of fault finding but we did replace the pre filter and also the main filter was replaced too with all new O-rings.
You can let the engine idle but if you rev it and then stop the engine shakes a little and you can see the air bubbles in the pipe.
Does anyone have any ideas what might have failed here or which areas we should check? What are usually the common things that go?
any help or advice is highly appreciated
