The pump flows 55 gallons per minute. It is used in conjunction with the stock LS mechanical water pump. This seems like a lot to us!
A really cool feature is the built in Radium Engineering FCST integrated surge tank/fuel system. The FCST system features an internal fuel surge tank with a low pressure, high volume lift pump that keeps the smaller surge tank full at all times. The surge tank contains 3 Walbro F90000274 high volume ethanol rated high-pressure pumps that keep the engine fed.
The FCST system is simple, lightweight, clean and ensures the engine will never starve for fuel no matter how large the lateral and longitudinal g-forces are.
You can see the pillow ball mount and the rebound adjuster for the Stance XR3 3-way adjustable rear shock as well.
