I have some 2.75 ID Federal hose. It is all new and never used just a little dirty. Its rated as a coolant hose but I have been using at my turbo to intercooler connection since I did my steed swap. Its held to 40psi no problems. I'm pretty negotiable on the price but since I have to put one $15 + shipping per foot. I have lengths of about 3' down to what ever you need.
