Motobilt has become well know for the aluminum fuel cells we manufacture. We often get asked for parts as well. The 12 Bolt D-Ring Fuel Cell Cap Assembly is what we use on our fuel tanks. The kit is a 12 bolt design with a twist on/off cap. This is the common 12 bolt design used on many different fuel cells. The kit is an all steel design. This fuel cell neck cannot be utilized for remote fill applications. The fuel cell pictured is not included. It is to show how the cap assembly mounts.
