Default Re: What size / type of nuts are used to fasten the gas tank to the bicycle?

There are two styles of tanks.
The larger 3/4 gallon uses 6 mm 1.0 nuts that are the same size as your motor mounting studs or sprocket nuts which is easy to check.

The smaller 1/2 gallon tank uses 5 mm 1.0 nuts.
