I am cleaning up rust from an apparent leaky battery from previous owner/s. When I removed the battery tray there is a white tubing coming out of a black rubber grommet of sorts from the fire wall . The pic shows the lower left corner. The tubing was not attached and rather brittle. I searched a few sites and to no avail a solution. There is also another tubing towards the center of the engine that also is not attached. Any one have any thoughts?
