Marin postulated:  

 

You don't say if this particular Racor is only in the fuel polishing

system or if it's also a (or the) filter for the engine itself.  If it's

in the fuel line to the engine and there are no bubbles in it when the

engine is running, and you have not had any problem with air getting

into the fuel feed to the engine (which you say you haven't), then I

would suspect the bubbles are coming from some component of  your

polishing system.

 

 

Scott adds:  Marin, you are spot on!  The filter is dedicated to the fuel
polishing system and feeds the selected tank, so my risk of supplying air to
the engine is zero.  There is risk of loosing prime in the suction pump (I
believe the pump is sucking fuel through the filter, not pushing it through.
So, if enough air accumulated in the filter I guess it could cause
cavitation in the pump.  I'll pull the top soon and look.  

 

Thanks for all the hints and advice.  Scott
