I found a crack/leak in the section of fuel hose that runs from the fuel pump (T) to the top carb. I'm going to go ahead and replace all the fuel hoses from the fuel fittng to the filter/pump and to both carbs but I want to make sure I get the right hoses. My OEM manual does not say anything about the type or size of the hose and I bought my motor used and have no idea if the last person who replaced the hoses put the right type on there so I don't necessarily want to go by the old hoses. Can someone tell me exactly what I need to buy? The motor is a 1979 100hp Johnson. Thanks!
