The modern fuel system is electronically controlled by on-board computers. It is designed to adjust and optimize the air/fuel ratio that is delivered to the engine as driving conditions change. GMB Fuel Pumps are essential to delivering the required amount of fuel from the fuel tank to the engine. Each GMB Fuel Pump goes through 3 points of inspection; at the development stage, manufacturing stage, and prior to shipment to our customers. This ensures the quality and optimum life of the Fuel Pump.
