Hello my outboard is leaking fuel at the plunger cap on all 3 carbs and has basically melted the rubber. Should there be file leaking there when Itls running? I’ve got new rubber plunger plugs in order. I didn’t know if I need to dig deeper as to why fuel is leaking or if Itls suppose to have some fuel and the plug is there to prevent from leaking.

since we have no idea what F40 you are talking about,
I will guess that the part you are talking about is higher than the fuel level should be in the fuel bowl of the carbs when normally operating.
so maybe the floats/needle & seat are not sealing off to control the fuel level properly.
But that is just a guess

thank you for responding!
but the F40 says it is a 4 stroke, but do you have any idea how many years and models there are for F40s.
they are not all the same.
this is why it is best to post the complete model ID of you motor when you ask questions about it

From the year 2000 through the end of 2006, Yamaha USA alone offered 48, yes 48, different F40 carbureted models.
Outside the USA there were even more F40 carbureted models offered.
There is almost no way of our knowing where in the world any particular poster resides.
