Glossary “fuel injection (FI)” Definition:
Term used for fuel-injection system.

Glossary “fuel injection system” Definition:
System that sprays fuel under pressure into the intake manifold or directly into the cylinder intake ports, allowing more precise control of the air/fuel mixture for improved performance, fuel economy, and reduced exhaust emissions.

Glossary “fuel injector” Definition:
Mechanical or electro-mechanical device that meters fuel into an engine.

Glossary “fuel line” Definition:
Rubber or metal lines that carry fuel from the fuel tank to the carburetor or injectorand return fuel not used by the injectors.

Glossary “fuel log” Definition:
