OK as some here may have gathered from the variety of issues my engine has that it is in need of a rebuild, if not then ya I'm rebuilding an omc115 from a jet drive, basically the same engine as an outboard, but I digress. Now on the carburetor there are the obvious fuel lines, but there are also a set of very thin tubes, for a size comparison I would say they're about the same size(od&id) as a sour straw(sorry for the candy reference, try 3/16 od and maybe 1/16 id) I cannot find them on the parts diagrams and I don't know what they do, they start between the barrels, and connect the two carburators, but don't seem to connect to anything else, are they part of the oil injection, which was disabled some time ago, and can be discarded, do they serve some function that i don't realize, equalize pressure between the carbs(not likely in my book), or perhaps some kind of vent? idk I'm at a loss, i can probably get a picture at some point if that will help clarify also it is a 1994 crossflow v4
