This is the line that has short rubber at its terminations, that are connected by a short much smaller diameter rigid line.

Mine was quite brittle, and it snapped while I was removing the manifold in order to change the VVT solenoids. I replaced it with a single rubber hose when putting the engine back together. But, I'm thinking that the smaller diameter rigid line was there for a reason...Like speeding/strengthening the vacuum for the changeover vacuum system.

Does anyone know this reason? I'll go to the dealer and see if I can still order one, make one, or something, if it effects the working of the changeover vacuum pump.

Picture of the piece in question:

The shorter hose that runs to the vacuum pump for the changeover shift rod.

Those hard plastic hoses were a bad idea. They start crumbling to pieces with age whenever you touch them or try to do any repair jobs on the engine. Follow those lines and replace them with silicone hose and you’re good to go.

And, they are priced out of this world! I'll start looking for silicone hoses...
