  • Fuel leaks.

What lines or pipes connect the engine to the fuel tank?

For example, take your car’s fuel hose — aka fuel line — they’re rubber, metal or plastic pipes through which gasoline passes from the fuel tank, where gasoline is stored, to the fuel pump. From there, fuel is squirted into the engine’s combustion chamber via fuel injection or a carburetor.
