Could you let me know if this Monza cap vents/breaths at all or it is fully sealed? The one I am lookig at is FF-M-2-C
The Monza and Aston fuel caps are all vented.
There is a small, about 2mm, hole in the brass plate which holds the seal.
If you require a cap that does not vent a blob of solder can be used to fill the small hole.
