Fuel Tanks and Fittings
Minis used either vented or non-vented gas caps, depending on destination of export. All saloons have a vent incorporated into the tank, and can use either type cap, Van/estate/pickup models do not have an integral vent, and will require a vented cap. "Smog" models require a non-vented cap for smog law compliance. Non-vented caps tend to leak less than vented caps.
