Installed the Marshall 2 stage regulator propane system June 14 2009

Today I got around to replacing my propane system, with a Marshall 250 2 stage regulator with safety pigtail flexible hose with connectors. I went ahead and wanted to make it rigid so I began with a 12" 3/8" black pipe between my newly installed 3/7" rubber hose metal braided hose I installed a flared swiwvel 2/way connector. This regulator allow the stand by tank to kick in if and when the #1 tank empty. It seems as if one of the pigtail leak when moved, so I may have to end up replacing it, but I guess time will tell. I replace the propane system so I would not run a risk of fires, so I wont take any chances.
