These refueling kits are designed specifically for the Radium Engineering FCST. The FCST does not come standard with any of the parts in these kits. As described below, the Radium Engineering refueling kits come in a few different varieties.
NOTE: "Complete" refueling kits include a dump can, as shown in photos below.
COMPLETE REFUELING KIT, REMOTE MOUNT, 1.5IN DRY BREAK
This option works for vehicles that require a quick-fill dry break mounted remotely from the fuel cell. The provided dump can features a leak-free dry break probe for quick fuel filling. The included flanged vented dry break receiver typically mounts to a body panel. A 1.5" fuel filler hose attaches to the provided Radium FCST mounted fill neck elbow. Unlike pressurized systems, this unique dry break configuration is permitted for most sanctioning bodies. A proper vent kit secures directly to the provided quick-fill 12AN DSV. 
NOTE: This refueling kit is not an option if using an older Radium 20-014X-XX FCST in conjunction with a fuel level sender. However, if a fuel level sender is not used with 20-014X-XX FCST, Radium 20-0439 can be installed in the fuel level sender port to permit the required 12AN ORB vent port. The standard 8AN ORB female vent port on the 20-014X-XX FCST can be plugged with Radium 14-0150.
