Part Number: 20-1047
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 20-1047 is an FCST-X remote fill neck with a 75° elbow for the 1.5in filler hose.
The elbow rotates 360° at the 24AN hose end so it can be clocked in any direction, or it can be removed to attach a 24AN filler hose. It's typically used with a body-mounted remote filler (not included).
