A remote-mounted fuel filler sits away from the fuel cell, typically on a guard or body panel, and is made up of three parts: the remote filler on the vehicle's exterior, the remote fill neck on the fuel cell, and the filler hose joining the two.
This Radium Engineering fill neck bolts to the 6-bolt fill flange on Radium FCST fuel cell surge tanks and connects to 1.5" ID filler hose via a straight barb. It is sealed with an FKM gasket and fitted with an FKM flapper valve, and is used together with a body-mounted remote filler.
