I was getting ready to order my Silicone Vacuum Hose kit when we noticed my friends T66 Dawg was actually vacuuming/boosting (only at .7 bar!) the Silicone Vacuum Hoses shut. Just to clarify, its like plugging one end of a hose and sucking through the other end. The hose pinches itself off. Has anyone else experienced similar problems? I'm debating whether to get the hoses now. Any info. would be great!
