Fuel System

The fuel system delivers fuel to the engine for combustion. It consists of components like the fuel tank, fuel pump, fuel lines, and fuel injectors. A properly functioning fuel system is essential for optimal engine performance and fuel efficiency. 

Cons of Delaying Maintenance: Reduced engine power, increased fuel consumption, engine damage, fuel leaks, fuel pump failure, injector clogging, and potential for fuel pressure issues or fuel line leaks.
