    Hey guys, so my boat ('85 210 Monaco, 230 hp alphaone) is currently at the marina in order to resolve a hard hot start issue (boat turning over strong but not starting after sitting for a while 20-30min?).

    There is a clear/yellowish fuel line that connects to the carb as seen in the picture, that looks as if it always has fuel in it. Someone has mentioned this is a fuel pump issue (fuel pump diaphragm has failed) and that replacing the fuel pump is the first step. Can anyone confirm this is an issue?

    I have already given the go ahead to do a carb rebuild, but I am not sure it is necessary. Should I go with fixing this fuel pump or just do both?

    Yes the line is a safety device to keep explosive fuel out of your bilge when the fuel pump craps out. It should normally NOT have fuel in it.

    Thank you for clarification!

    Is this what could be causing vapor lock or a hot soak??? How does this line filled with fuel cause this issue?

    What do you recommend i do with regards to carb rebuild?

    Put a new marine fuel pump on it and test drive it.

    Diaphragm has ruptured and dumping fuel down the carb. It's flooding your engine when motor is off. Never hurts to rebuild a carb.

    Awesome, thanks for the fast input guys. Called the marina and they are going to quote the work needed to replace the fuel pump. I think I'm just going to have the fuel pump replaced and carb rebuilt though as it has almost certainly never been done by my grandfather who has owned the boat since 1985...
