      Ain't no subtitute to AC Delco

      Posted by Charles Lowe on 31st Aug 2015

      I bought a couple of check valves in the HELP! section at Autozone. I tested them when I got home with my mity-vac and one failed at 20psi and the at 25psi. I run 25 psi of boost. Both of the Autozone brand failed. I tested both my AC Delco check valves, no problems up to 30PSI(as high as my mity vac will pump).
