Small Fuel Line

[jamepc]

Hello,
On my 2002 Islandia with a 240 Mercury, there is a very small fuel line, probably about 3/16 OD, that connects to three points on the starboard side and 2 or 3 points on the port side. The lowest connection on the starboard side has a tee and the line continues another 10" or so and just dangles in the bilgeleaking fuel. I cant see anywhere this line use to connect to. Can someone please explain the function of this small fuel line and where all the connection points should be?
Thanks for any help!

I don't have the answer, you'll get better results is you post this on the Mercury powered boats section.

I tried to post this question in the Mercury Powered section however I got a message that it won't post until a moderator approves it.
While I'm waiting for that, here a little more info.
It looks all these 1/8" barbed connections that this small tubing is attached to is coming off the throttle body/intake manifold area.
The three barbed connections on the starboard side are all connected and the line loops over to the port side and connects with 2 other barbed connections. Also on the port side are an additional 2 or 3 barbed connections however the aren't connected together, rather they have their own 5" line that loops them back into the block. Additionally, there's one more 1/2" barbed connection on the very bottom port side that's not connected to anything. And as stated in the original post, the barbed connection on the lower starboard side is connected with a T but the bottom of the T is open and connects to nothing. Both these unconnected fitting have fuel dripping from them.
It's real hard to see being that the engine is stuffed in an Islandia and all the other components block most of the view.
Thanks again for any help!
