Jack Stepongzi saw a need for CNG inspectors and decided to become that solution. He started his company, Certified CNG Inspector, in 2012. Jack travels everywhere east of the Mississippi River inspecting, repairing and doing CSA training on refuse trucks, buses and semi’s.
American CNG has been working with Certified CNG Inspector for about four years providing high pressure components such as OMB valves and receptacles, cylinders, regulators and various other hard-to-find parts. Jack has an arsenal of connections in this industry that we are lucky to be a part of. With this list of vendors, he is able to find parts for systems that aren’t being built anymore such as Mainstay or Worthington.
We are happy to work with Jack any chance we get! His high standards for customer service definitely keeps us on our toes.
Hi Jack I have a 1999 Ford Crown Vic Police Interceptor dedicated CNG and looking to convert the 3000psi fill nozzle to 3600psi-please assist
