I have acquired a pressure washer with a GX390/420 (says 15hp) Honda engine. Besides the main fuel running from the tank to the carburetor inlet, there is a second smaller hose that runs from about 3/4 of the way up the tank to the intake above the carburetor. This looks like some kind of a vent hose, but it you fill the tank up above that level fuel run straight into the engine !
What is it purpose and how do you prevent the fuel from a full tank from running into engine and causing it to hydro-lock ?
Looking at various pictures of these engines (and clones) some have this hose and some do not.
