I see. But that would mean the muffler would fill with fuel if it's the vent line. Or how do you know when you're full? I could return the electric pump and buy a manual pump to count turns I guess. It was the same price so I grabbed the electric version.

Thanks for the replies. I guess I'll just have to build it how I think it should be and start adding pieces in line. I just figured someone would have posted instructions about this or a website on setups, as it definately wouldn't be intuitive to a new glow builder. Especially when nothing's listed in the manuals.
