The Radium Engineering fuel cell fill kits can be used on any cell that uses a 6-bolt 2.18" (55mm) bolt circle mounting flange.

The 20-0147 Fuel Cell Remote Mount Fill Neck is multi-functional and is primarily used with a body-mounted remote filler, as shown in the picture below. The fill neck has a machined barb for 2-1/4" filler hose (available ). The kit includes a check valve for role over protection. If circumstances ever change, ie: the fuel cell is moved to a different vehicle, 20-0148 Fill Neck Cap can screw onto 20-0147 Remote Fill Neck for direct filling. Note that even though the sealed roll-over valve can be removed for direct filling, the fill neck has a minor machining obstruction from the valve.  

20-0148 Includes:

-Anodized and Laser Etched Aluminum Cap
-Viton O-ring Cap Seal
