thanks for your response about the switch over valve. I think I understand what you are saying but I do not have the valve lines so I can only go by what the pictures in my Haynes manual show. In the manual it appears to be a valve with two hoses running to it but when I try to buy this valve auto parts stores show it with three hoses and a electrical connection. Does anyone have an extra of this valve they would be willing to sell? More info on the valve itself would be appreciated. Also I do not have a clue about what you said regarding the "Turbo Over Press Easy Diy"

thanks
