Os gf40 4 stroke basic question
 

Hi there,I've recently bought an OS GF40 and I have a beginner question: 1 pipe from tank goes to carburator, the 2nd one is for refuel and then the third normally goes to the exhaust working for pressure. As I read in the manual, OS GF40 doesn't need it but the picture show the third tube so I was wondering where shoud I connect it or if just I have to leave it not connected. Should I also connect a silicon tube to the PCV ? May someone post a schema of connection from tank to engine.

Many thanks.

I only use 2 fuel lines. One from the clunk to the carburetor, and the other from the vent to the muffler. I refuel by removing the line at the muffler. If you use 3 lines, be sure to plug the refueling line when running the engine.

I'm talking about os gf 40cc ...there's no muffler pressure to connect
