FCST 1 Surge Tank Pumps 1 Lift Pump Included Walbro F90000274 E85 Radium Engineering

WHAT IS A FCST?
The Fuel Cell Surge Tank is a drop-in fuel pump system for Radium Engineering's popular fuel cells or any cell that uses the industry standard 6x10 24-bolt fill plate bolt pattern. The FCST is designed to protect EFI vehicles that experience fuel starvation. It is NOT a glorified trap door box with baffles. It features a true dual-chamber fuel tank utilizing a single lift pump and up to 3 surge tank pumps all packaged inside the fuel cell. It provides all the benefits of a traditional external fuel surge tank without safety concerns and plumbing complexity. 

IS THIS COMPATIBLE WITH MY FUEL CELL?
To install a Radium Engineering FCST into a fuel cell, the following criteria must be met:
1. The cell must have the industry standard 6"x10", 24-bolt flange opening.
2. The opening must be on the top face of the fuel cell (i.e. not a side face).
3. The cell depth must be at least 7.7" (196mm) measured from the outer top face to the internal bottom face.

20-099X-XX FCST

The 20-099X-XX Fuel Cell Surge Tanks utilize new design features that reduce overall weight by 35.3%. These new additions also improve assembly time. They also use stronger stainless steel lift pump mounting brackets. Furthermore, they are compatible with Radium Engineering's shrouded fuel level sensors.

FCSTs are available with and without fuel pumps included. The lift pump is always matched to be the same style pump(s) found inside the fuel surge tank canister, with exception to the brushless Ti Automotive E5LM variation (below). Any option that lists "Pump Included" comes pre-assembled with new fuel pumps and filters installed.

If "pumps not included" is ordered (shown above), fuel pumps must be sourced separately. A filter sock will only be required for the lift pump as inlet filters are already supplied for the surge tank pumps. Also, there will be enough components included with this option to use up to 3 pumps in the surge tank. Depending on the setup, some parts may not be used.
