Subaru STi Spec C Anti Surge Fuel Pump Assembly Chassis & Suspension_Wheel Bearings & Seals but lets not stop thereThe Subaru Impreza fuel tank design is flawed particularly when running below half a tank of fuel. Its possible to encounter fuel surge on hard cornering and spirited driving as fuel moves around the fuel tank and away from the fuel pump. Fuel surge occurs when the fuel pump sucks in air as it is no longer submerged with fuel. This results in a fuel cut which from a driving perspective is quite aggressive as power from the engine is immediately cut.
