Rubber fuel line through engine tinware - 6mm

Rubber fuel line through engine tinware - 6mm

This is just a small rubber, but very important. It sits in the front plate of the engine tinware and through it is the metal fuel line.

If this rubber is missing, vibration can wear out the fuel line and cause dangerous leaks. So check if it is still present and replace it if it shows wear. 

Of course, this rubber can also be used for other transit purposes.
