I did not know that any Morgans had air pumps fitted as you describe but then I am no expert on Morgans... I did own an 80`s 911 which has an air pump and pipework connected to the cylinder heads just after the exhaust valve. I think the idea was to provide air in order to assist burning of fuel that had stopped burning in the combustion process due to the lack of air, and thus allowing it to burn up in the exhaust system, to clean up the eventual tail pipe emissions...?
