Fits through the smallest tank fill holes. Fill time slow but still reasonable.

Even the single small fill hole in the top of the Davide "vapeonly" tank can be used to fill the tank with this needle, as there is room for air to escape around the needle. This needle is called a 20 gauge. I normally use a slightly larger smaller gauge size that doesn't fit through the smallest holes. This 20 gauge x 1 1/2" needle solves the problem.
