I love this guy! Great teacher!!

Nice explanation. I always wondered why there's a spring

Well done, thank you!

Not sure about the Philippines, but in most of the developed world gasoline fuel tanks have an evaporative emission system. Which means the tank is sealed. And vapors go through a charcoal canister. The reason for this is so that fuel vapors do not escape into the atmosphere. That is a large source of pollution and this way stops that. The engine computer controls when the system is purging or sealed or open

Thank you teacher. Perfect.

Another great video. 👍

Nice explanation of the fuel cap .The cap is a pressure-vacvum cap Most cars have a positive pressure when the cap is opened . My car used to also have a positive pressure and hiss when the cap would be opened . Lately i noticed it has no pressure , and I get smell of gasoline in my car . So wondering if it is related to the fuel cap . Do let me know your thoughts ... Thanks again

Thanks for sharing sir great video. Now I understand better how this fuel cap works. It allows air in as you explained which equalizes the pressure and vacuum. yes?

Present again Sir 🙋 Keep Safe Always

Thank you for explanation,,👍

thank you

Great explanation....well done

Very useful information 👍🏻

yo are the best!

Hello, Can you tell my why a LOT of air pressure is getting pushed out from my tank when I take off the fuel cap.

What are the gaskets made out of ? I need to make one for the cap on a 1969 Chevy van

Sir, Can you please tell me how the power of glow plugs shut off of 4d56? A vlogger told me that it comes from the temperature sensor which has two functions: monitor and temp sensor that cuts power to the glow plugs. Since the temp sensor is submerged in the coolant, how much is the coolant temperature so that it activates the sensor so that it shuts off the power for the glow plugs?
