Radium FCST & FuelSafe Fuel Cell - How It Works & Proper Installation
This listing covers the Radium FCST-X Fuel Cell Surge Tank in five pump styles, supplied without pumps (SKUs 20-1990-00, 20-1992-00, 20-1991-00, 20-1993-00 and 20-1995-00). The Walbro F90000267/274/285/295 version is also available with Walbro F90000274 pumps fitted: one, two or three surge tank pumps plus one lift pump (SKUs 20-1992-01, 20-1992-02 and 20-1992-03). Choose the pump style and pump package from the variant selector. It is a universal fitment component designed to integrate with fuel cell installations in professional motorsport builds including road racing, endurance, and time attack applications.
On the pump-included versions the surge tank pumps come pre-installed. The lift pump is packed loose so its height can be set to suit your fuel cell.
Important: -6AN ORB fittings are required for installation and are not included. The fuel cell is sold separately, and so are the fuel pumps unless you choose a pump-included version.
Key Features
- CNC-machined billet aluminium construction with anodised finish
- Supports single or dual pump configurations
- Multiple -6AN ORB (O-Ring Boss) ports for versatile plumbing
- Integrated fuel level sender provision
- Compatible with petrol, E85, and alternative fuel types
- Universal fitment for fuel cell applications
Full application compatibility and installation notes are provided in the tabs above. Please confirm your fuel cell configuration and plumbing requirements before ordering.
