Vacuum line?

[TnTommy]

Just bought this pontoon boat this summer it has a 2000 50hp evinrude fuel injection motor. I found a line running under oil filter that goes to nothing on one end, on the other end it goes through a filter then splits with one split laying on top the thermostat open and the other split goes into top of engine see pics, just wondering what it is maybe a vacuum line?

I have this service manual which is close to your motor...(40)

Lots of illustrations and if you can describe it better or make a YouTube video I'll be able to analyze it better.

Definitely looks fuel related and hopefully someone will come along and answer your question.

You could also go to the Suzuki forum because I believe that is the maker of that outboard.

Are you having trouble with this motor or just wondering.
