A remote fuel filler setup has three parts: the remote filler (housing and cap), the remote fill neck that connects to the FCST or fuel cell, and the filler hose that links them. The 20-1027 is the remote fill neck for the FCST-X – a simple straight 1.5in machined barb that bolts to the FCST-X 3-bolt filler flange.
It's typically used with a body-mounted remote filler such as the Radium 20-1005-V or 20-1004-V (not included). The fill neck is sealed with an FKM O-ring and secured with stainless hardware.
