The Monza fuel cap is one of the best looking fuel caps for the Classic Mini. It is smaller than the Aston cap and is very highly polished with a flared centre. It is a sealed and vented cap that negates the need for the standard stainless steel locking cap. It features a flip top with a push button opening. The design was conceived for function as it allows faster filling of the fuel tank during racing. It was used at famous race tracks such as LeMans and Monza, hence it's name.
