Seems I have an air leak somewhere in the fueling system of my W210 E300d; resulting in no fuel in the system when I come to start and then having to crank the engine over for ages for it to prime up and fire...

Once running it's fine though.

Before pulling the whole fueling system apart, is there a usual list of suspect areas I should look at to start with?

Can't see one, but is there a manual priming system on the engine somewhere? (saves my battery and that of the other car I need to get a jump start from)

Thanks...

Do look in the pipe from the fuel filter to the engine for air bubbles, it should just need new O rings,50p each from MB

There's an O ring between the pump and shut of valve, that gets hard and no longer makes a seal and let's air in, and also as Malc above.......

start with the clear pipe connection furtherthest back to the tank - fix the bubble there, and see if it fixes the rest.

replace all the orings as a matter of course.
