2005 Tohatsu MD40 3 cyl 3 carb. Bottom carb has fuel pump on it. When I pump the bulb gas came out of bowl gasket and throat of carb. Took fuel pump apart both diaphrams look ok so ordered bowl gasket and needle valve. Seat is not replacable and appears fine. Old needle valve appeared to be fine. Installed parts and bowl gasket doesn't leak but still comes out of the carb throat. I don't feel like I'm pumping the bulb too hard and the whole reason it was discovered was because the motor ran low on power and it appeared the bottom cyl was flooded. Short of ordering fuel pump diaphrams not sure what else it could be. I looked the existing ones over carefully. Thought I had ordered them just in case but apparently I didn't. Have not tried running yet because of rain but will try tomorrow. At a loss here. This is the one with the fuel pump mounted on it.
