I received the Vortex screw top gas cap ............ THANK You ZG, but I have decided that it is just not for me. You never know about something til you try it. I will offer anyone that wants it the same deal that Jay offered me ........ FREE! I paid $12 in shipping to him, so I will ship it to anyone in the USA for the same price. If you are outside of that, let me know where and we will figure out the shipping cost.
