Fuel System Components and Functions

The video tutorial covers the fuel system, its components, and their functions. It explains the importance of the fuel system in delivering fuel to the engine, comparing it to the human vascular system. The tutorial details the basic components, including the fuel tank, pump, lines, filter, injectors, and carburetors. It highlights the evolution from carburetors to fuel injectors for better emissions and fuel economy. The video also discusses the types of fuel lines and the necessity of clean fuel for engine performance.

What are the three essential elements needed for an internal combustion engine to operate?

• Air, fuel, and water

• Air, fuel, and spark

• Fuel, oil, and spark

• Air, oil, and water

What is the primary function of the fuel tank in a vehicle?

• To filter the fuel

• To pump fuel to the engine

• To store fuel

• To mix fuel with air

What is the role of the sending unit in a fuel tank?

• To measure fuel pressure

• To pump fuel to the engine

• To filter fuel

• To indicate fuel level to the gas gauge

Where is the fuel pump typically located in newer car models?

• Attached to the engine

• Inside the fuel tank

• In the trunk

• On the frame rail

What type of fuel line is used for high-pressure areas between the injection pump and injectors?

• Medium weight lines

• No pressure lines

• Lightweight lines

• Heavyweight lines

Why is it important to filter fuel before it reaches the engine?

• To cool the engine

• To reduce emissions

• To prevent clogging of injectors and carburetors

• To increase fuel economy

What material are most disposable fuel filters made from?

• Plastic

• Paper element

• Metal

• Glass

What is the main advantage of fuel injectors over carburetors?

• They are easier to install

• They provide better fuel economy and lower emissions

• They require no maintenance

• They are cheaper to produce

How does a fuel injector operate?

• It opens and closes with an electric signal

• It uses a mechanical lever

• It relies on air pressure

• It uses a manual pump

What is a common issue with carburetors that fuel injectors help to eliminate?

• Frequent tuning and rebuilding

• High production costs

• Complex installation

• Increased fuel consumption
