Radium FCST Lift Pump Extension for Deep Cells

Radium FCST Lift Pump Extension — For Deep Fuel Cells

This extension kit is designed to mount the Radium Fuel Cell Surge Tank (FCST) lift pump to the bottom of deep fuel cells. The standard FCST lift pump brackets are designed for fuel cells no deeper than 10" (measured from the underside of the fill plate to the bottom of the lift pump filter sock). This extension kit adds a further 8" of reach, accommodating fuel cells up to 17" deep.

The kit includes two 5052 aluminium brackets that are laser-cut, formed, bright-dipped, and Type-II anodized. Simply cut to the required length using a band saw, cut-off wheel, or similar tool. Note that longer hose and/or wiring may be required depending on the installation depth — contact Radium tech support for further guidance.
