Give your Mini that retro look while you keep your pricey fuel in your tank where it belongs with this locking, old-style gas cap. Comes with two keys. This is the original round-top shape of petrol cap that was so popular on the 1960-1970s cars. Made in the UK by Wilmot Breeden. Because it is vented, this cap is not recommended for fuel-injected cars, which have a sealed system.
