ALSO BUY A PVTOOL if you don't have one.. listed under "PVTOOL"
We purposely have the # "PVTOOL" cheap so you both have one for future use and maybe a mechanic if your using one will need it and probably not be aware of them etc.. but so you will do it right to start with , get one, otherwise you most likely stuff up a new proportioning valve.
