The pressure tester I purchased from J.C. Whitney is specifically for CIS systems. It is designed for the higher pressures than other injection systems and has all of the necessary fittings including the valve that lets you isolate the CPR (plug & play). In addition, the unit came with instruction that were very helpful. Woody __________________________________ Do you Yahoo!? Yahoo!
