I have been so disgusted with my micron guage and vacum pump holding a vacum for some reason just wont happen. I have been trying to eliminate some possibilitys. I will hook my vacum pump up to my manifold, then hook blue guage to micton guage and leave red hose on manifold. I can pull my micron guage down below two hundred microns then.valve off my blue hose and it starts climbing. Put in new rubber gaskeys in.hose. Guess it has to be the micron guage... Or could.the manifold be the problem. Usong the cheaper jb micron.guage
