I had trouble with my releaser, 12x12x18x6 model 12-280 lappierre. One side would charge to 26"+ and the other side only to 16" vacuum. I tore it apart and cleaned it with hot soapy water. I was given a care guide from the guy I bought it fro finally. I ordered the right lubricants as I was using a food grade grease called White Gaurd. After cleaning it I threw some olive oil on it just to retry it out of curiosity. Now I have No vacuum at all past the line that enters the manifold with the pistons. I'm having a hard time thinking it's because of lack of grease. Anyone have a diagram of gaskets and such?
