I have a 1985 Mercury 50 hp outboard. It has dual wma3 carbs. We had a severe leak in the lower carb at the end of last year. Fuel was coming up through the jet and out the front of the carb. I decided it was probably a good idea to rebuild the carb and fuel pump. However after doing this we are still getting the same leak. It does not pour out but is a constant drip when the fuel line is connected.
In my trouble shooting I left the bowl and float off and manually held the needle in place. However I still get fuel leaking. My first thought is fuel getting between one of the gaskets on the fuel pump and down the hole to the right of where the needle sits. I did not put any sort of seal the or anything on the fuel pump gaskets before I put them on. Should I have put something on the gaskets this?
