What about the carburetor? Could it be I need to put a thermal block between the carb and the aluminum intake manifold?
I doubt your theory re the 'pressurised vapour' however in any event I would have put the filter on that vertical section of fuel line above the fuel pump.
If it WAS vapour under pressure in the filter it would vent itself through the carb as soon as the fuel in the fuel bowl dropped its level.

I also doubt the necessity to put in a thermal block.

My 2 cents worth.
