The FiTech HyperFuel Single Pump G-Surge Tank is designed to be used in vehicles that have fuel starvation issues when being used in extreme lateral G-force environments. This could be due to poor fuel tank baffling in the existing fuel tank. The G-Surge eliminates that problem. The pump in the G-Surge never gets uncovered because it receives a steady supply of fuel from your existing fuel system as well as the fuel returning from the fuel injection system. So your system maintains a constant flow of fuel. Since the G-surge is constantly circulating fuel to and from your tank, your fuel pump stays cooler and will have a longer life. The fuel pump noise is also muffled by being submerged in fuel 100% of the time. The G-surge is also the best way to provide the necessary increase in fuel volume when adding a power adder, such as boost or nitrous to your engine.
