A vehicle’s fuel system typically consists of a fuel pump in the tank, a fuel filter, and injectors (one per cylinder). The vehicle’s central computer manages this system and is generally reliable. But if the fuel system is not regularly maintained, fuel consumption will increase over time, and the system could even fail. That’s why it’s crucial to follow the manufacturer’s recommendations. You can trust the maintenance of your vehicle’s fuel system to a certified NAPA AUTOPRO technician.

The technician will determine if the fuel filter needs to be replaced or if the injectors need cleaning based on the recommended maintenance schedule. Injectors spray the necessary quantity of atomized fuel under high pressure for combustion in the cylinders and are a critical component. The spray nozzle is as small as the head of a pin and can get clogged if dirt gets stuck in it. During a cleaning, your certified NAPA AUTOPRO technician will remove any deposits, restoring the engine’s power and performance and improving fuel economy. Direct injection fuel systems in late-model vehicles require meticulous maintenance. Failure to maintain the fuel system according to the manufacturer’s recommendations could cause the Check Engine light to come on and damage to other parts controlled by the vehicle’s central computer.
