These Aeroflow Performance Surge Tanks are designed to prevent starving the fuel pump by increasing the fuelling capability of the fuel system. It is usually installed in vehicles that potentially can experience fuel starvation due to fuel sloshing around in an inadequately baffled fuel tank/cell. While this can occur in any vehicle when the tank is not fully filled, it is more frequent in vehicles subject to violent changes in directions such as autocross, off-road, drag racing and other types of racing that involve high g-force. The primary fuel pump in the vehicle's main fuel tank will no longer directly feed the engine. Instead, the internal fuel pump will now be used to fill and maintain the level of fuel in the surge tank itself. Using a surge tank will now require new external fuel pump/s to be installed after the tank to supply fuel to the engine.
