Hello all,

I'm new to the world of diesel vehicles and I've just completed a fuel tank flush and complete flexible fuel line replacement including the intake screen and both filters on my 240D. I bled the car using the newly-installed Bosch primer pump and by cracking the hard lines at the injectors and cranking. The car appears to be running phenomenally.

I noticed a small amount of air in the prefilter and was wondering if this amount is considered normal. Despite continued pumping, running, and manipulation of the prefilter I cannot seem to get this last little bit of air out. Picture for reference.
