The fuel pump in your car, truck, or SUV, is an integral part of the fuel system. The fuel pump pumps fuel from the gas tank into your engine. It is recommended to inspect the fuel pump at regular intervals defined by the manufacturer, to ensure optimal operation. If your fuel pump is failing, you may experience a loss of power, sputtering, or a vehicle that won't start, or run. If the symptoms are ignored long enough, the fuel pump will eventually fail and need to be replaced. The fuel pump is just one component of a complex fuel system that your vehicle depends on every day. If you're experiencing symptoms of a bad fuel pump, give S And S Inland Star Mercedes a call at 909-864-4701.
