Probably around 7/32" or 5/32". Either way it has to be smaller than 1/4" and larger than 1/8".

I think they might be 3/16". The easiest way would be to just take one off and take it in to your local auto store and ask. They'll be able to tell you in about 5 seconds.

The small ones are 6mm and the large ones are 8mm IIRC.

3/16" sounds about right actually.

Except anywhere you go to buy vacuum/fuel hose, it'll be in inches (and in fraction form).
