Inquiry (采购产品): Request for Information I am in the planning phase of overhauling a Pure water Trailer for the US Navy. There is no documentation or engineering drawings available. The pure water tank on the trailer has a Protectoseal Pressure/Vacuum Vent, Cat. No. 8542. In order to prepare written instructions to overhaul the various equipment on the trailer, I need a copy of the detail drawing, instructions to set and to verify pressure and vacuum settings, and recommended replacement parts. I also need the options available for any gasket material. Thank you. **** Hidden Message ***** Richard Yankowski Eastern Point Road Groton, CT 06340 USA Company: General Dyamics Title: Engineer Phone: 860-433-5473 Fax: 860-433-4166 E-mail: ryankows@gdeb.com **** Hidden Message ***** ryankows@gdeb.com
