The GMC fuel filter is one of the more important maintenance items in your vehicle, helping to keep the fuel system free of contamination. The proper care and replacement of the GMC fuel filter is more important than ever before, with the fuel systems in most modern engines using a fuel-injected design to replace the older carbureted type of fuel delivery. These systems are very efficient, delivering a precisely measured amount of fuel directly to the intake valves of the engine to enhance the efficiency of the engine combustion process, providing a cleaner burn of fuel for less waste. These efficient fuel delivery systems require a very clean supply of fuel to function well, with the tiny injector tip that is used to dispense fuel to the engine sensitive to contamination from even small particles of dirt or debris. The fuel and air ratio delivered to the engine is constantly monitored and adjusted by the vehicle computer to provide the best mixture for efficiency in the engine. If the GMC fuel filter is clogged or dirty, the delicate balance achieved by this system can be thrown off, causing performance problems in the vehicle. Even the modern and efficient fuel pumps used in today's engines are more vulnerable to contamination from debris.
