Gaffer.
Not sure if the 4 seat has the same filler cap as a 2 seat, but I had my 2 seat filler cap changed for the aero type. Good design with a morgan logo, it allows you to take the key out when open (no more marks on the paintwork), and resolves the old issue of refuelling - wider neck, it now goes in easily and quickly. Just have to be careful when it nears full as it will run over.
