Any auto parts store like Autozone, Checker/Kragen/Schucks, Pep Boys or NAPA. It is universal in design for all car makes/models. Cost around $20-$30. Good luck!



Good vacuum will read at least 15-22 in hg.

anyone know if the actron scan tools (specifically cp9145) measure vacuum (such as through a sensor)?
