Looking under my 4runner I noticed a hard line that has rusted through and need help identifying it.
This is on the passenger side right beside the cat. The lines turn up inside the fender to I'm not sure where. The other end transitions to flexible hose (behind a metal guard) and turns up into the body somewhere along the rear door. There are 2 parallel lines.
It obviously hasn't had fluid in it for awhile and vehicle performance has been normal and smooth. Can someone ID this so I can replace it?
