*****************************************************
On my fuelfilter installation which is the standard, one glas-filter
installation exactly as per Mk1 standard installation, I always have a more
or less big airbubble in the top of the filter; have seen this also on other
Europas. This airbubble stays there all the time also during flight and with
the electrical pump on.
I'm wondering if this is "normal" or indicates some small leak??
