Radium Engineering FCST Adapter 6-Bolt to 3-Bolt Filler

Radium Engineering FCST Adapter 6-Bolt to 3-Bolt Filler This adapter can be used to adapt any of the current 3-bolt fuel cell filler necks currently used by the FCST-X onto a legacy FCST that uses a 6-bolt hole pattern fuel filler. The adapter adds less than 1/2 inch of height to the filler cap or neck when installed.

To include the same safety measures as the previous models, rollover protection is built-in using the same one-way valve that legacy FCST fillers used. A new gasket is also included
