Ventilation [breathing]

1. A tank carrying ventilation though the filler neck requires a sealed cap [Non Vented]
2. A Tank without ventilation device requires a breathing cap [Vented Cap or a Cap with a breathing Valve]

As a consequence of the above, the two types of cap look the same as to size and working, except for the ventilation.
Make sure you choose the right cap and carefully read the manufactures instructions

Fitting instructions for Gates fuel caps are included in the packaging
