Radium Engineering Walbro F90000267/274 (E85) Pump Fuel Surge Tank (Pump NOT Incl)
A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. The FST fuel pump(s) directly feed the fuel rail(s). The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump supplied with fuel.
- This volume is maintained by the main fuel tank's pump as well as the fuel returning from the fuel pressure regulator.
- Excess fuel in the surge tank is returned back to the vehicle's main fuel tank.
- The surge tank also provides a quick and easy way to upgrade any standard fuel system without the need to modify the stock fuel tank or pump.
- This is an excellent fuelling solution for vehicles installing large fuel demand power upgrades such as forced induction.
