Please Help! Need to know what this hose is/was?

[Blue_Runner]

This is a mysterious hose update:

It was an easy fix. Just removed the "T" and had enough slack in the remaining tubing to bridge the gap and hook in where the "T" once hooked. Put a heavy duty zip tie on it real tight and I was done.

The only other thing I could do to this motor besides a rebuild would be replace the starter and solenoid just as a precaution. I might just do that if I ever get off my tail and sell this other motor! Not to mention my other 2 boats!
