LOL, Yeah I guess that make sense.  I have disconnected the Clutch from the A/C, nothing changed.  Vile I have steel braided hoses at the TBI (OEM) and hard lines down under the truck.  I obviously can not pinch off the hard lines but will I damage the steel braided lines if I pinch them off?  If I can ask what will this do?  I'm curious.  Does it raise the pressure in the system?  Thanks
