Description

Fuel Filler Cap for the fuel tank filler neck – pressed metal, two-lug bayonet fitting, non-locking and vented.

The cap seals the filler neck against fuel spillage and dirt ingress, and locates with a quarter-turn action on two lugs inside the neck. The vent admits air to the tank as fuel is drawn off, preventing the vacuum that would otherwise starve the fuel supply, so it must not be replaced with a non-vented cap where the tank has no separate breather line.
