Hi all,
I have been having the usual W202 problem of difficult starting due to air getting into the fuel lines and allowing the diesel to flow back to the tank overnight.
Usual thing, park it with the nose pointing downhill and it will start fine.
I have replaced all the clear plastic fuel lines with genuine MB parts, fitted new O rings all round, replace the rubber fuel lines with new ones, replaced the steel fuel lines.....still the diesel flows back to the tank overnight. The clear plastic fuel line to the fuel pre filter (near the main fuel filter) is always empty of diesel every morning. I have fitted a fuel primer bulb (as per old school Peugeots) which helps but fed up of having to use this all the time.
Is there any was of by passing the fuel pre- filter ???
