I have a 2000 Johnson outboard 225 ocean pro. I was changing the fuel filter inside the cover, when I noticed that there was 2 places fuel goes after the filter. There's the main *hose going to the carb but there's also a little hose that comes out of the side of the same hose. Does anyone know what this goes to/what it's for? I think it was disconnected before I replaced the filter.*
