I have to replace the hose. it goes to my heater but not sure of the part name. its the hose coming down off the plastic piece. have no heat. thanks

 

There is a product called "synflex tubing". It comes in various sizes. Trucks use it for oil,air and sometimes fuel lines.It is like a nylon material and can be used for vacuum lines also. Not sure of just what your line in the pix carries, but you ight be able to use the tubing there.

 

its for the heat for my 2000 Taurus se. Thanks for the info
