Tried this no change. If I slightly pinch the hose in my fingers it stops vibrating and still operates. Is there a buffer of some type I could put in the vac line to it. I thought about a small inline fuel filter. Would let the air through but slow down fluctuations. Would that work? I think a lot of it has to do with it not being a good vacuum gauge too, was on a hand vacuum pump. Not meant for this I am sure.
