What is gravity feed fuel system?
Gravity feed aircraft fuel systems
This is the simplest of fuel systems commonly found in high wing aircraft with a fuel tank in each wing. A gravity feed system is designed with the fuel tanks above the engine and propulsion system, with lines feeding the fuel from the tank to the engine via gravity.
Are Semi fuel tanks connected?
