The factory fuel system in your Subaru vehicle stores fuel and delivers it to the engineas it's needed. While fuel systems vary from engine to engine, they all have one thing in common. They have to deliver fuel to the engine's combustion chamber, and they need to control the amount of fuel that's delivered in order to maintain the optimal fuel-to-air ratio. Sounds simple, but there are many parts to the system, with each serving a key role.
The fuel tank stores the gasoline. A fuel pump draws out the fuel to direct it to your engine. With older vehicles, the fuel pump might be attached to the engine or on the frame; on modern models, it's installed within the fuel tank itself. The fuel filter removed contaminants from the gasoline before it gets to the engine. That keeps your carburetor or fuel injectors free of impediments that can clog them. Older vehicles may feature a carburetor, but today's models are equipped with the fuel injectors that improve efficiency and emissions.
