Greetings.
There are three rubber lines from the gas tank. The larger line from the bottom of the petc to the carb is the main fuel line. This is probably too basic to even post about but what is the purpose of the other two (one from petc side and one from fuel regulator on other side). Thanks.

Ones probably a vacuum line to open the fuel valve up when the engine is running and the valve shuts when the engine is off. Look and see if there is a "prime" postion on the pet****. The other I have no idea.
