1985 Brat non turbo.    I have a "vapor separator near the firewall, driver's side, (left, USA).   Fuel comes from aft low in the separator, leaves low to go to the carb.   Out of the top vapor returns to the tank.   Mine is opaque, probably from age.   Is it also a fuel filter, and should I replace it as preventative maintenance?   Part number 7420 72020 .

Yes.  It is a filter and vapor control and should be replaced periodically.  I am guessing you still have the original carburetor.  The vapor line is often capped/removed if an after market carb is installed.

The vapor separator is available over on ebay.
