OVERVIEW
The fuel cell subharness kit is a great addition for quicker pit stops. It is common for racers to have a spare drop-in FCST-X fuel pump module in the pit in case there is an issue with a fuel pump, electrical wiring, etc. With a subharness on both FCST-X units, the entire pump assembly can be swapped quicly without any tools.
COMPATIBILITY
-RADIUM ENGINEERING FCST-X (or FCST)
Each of the 26 preterminated 10awg wires has a unique identification labels associated with the FCST-X labeling. However, they can still be used with the older FCST that has slightly different labeling.

-RADIUM ENGINEERING RA-SERIES FUEL CELLS
Designed specifically to mount on the perimeter of RA-Series Fuel Cells. For another fuel cell to be directly compatible, the bolt spacing must be 3.6"-5.7" (91-145mm).
The bolt hole distance of the bulkhead mount is compatible with all Radium Engineering RA-series fuel cells. It can be mounted anywhere along the perimeter of the fuel cell. Furthermore, the mount can be rotated inwards or outwards for a 3in (76mm) location difference.

1. Install the labeled ring terminal wires to the FCST-X studs.
2. Install the mount using the fuel cell hardware.
3. Assemble the bulkhead connector to the mount.
4. Cut and crimp the contacts to the wires
5. Install the contacts into the connector.
6. Install the plug seals into all open cavities.
7. Assemble and populate the chassis harness.
