I have a Craftsman Model #919.152811, Twin Cylinder Air Compressor. 240 Volt, 125 PSI Max, 15.0 scfm @ 40 psi, 11.5 scfm @ 90 psi. The compressor builds air very slowly, but will eventually build and shut off at pressure. I believe I need both of the Piston and Cylinder repair kits #47. Does this Kit have all the parts necessary to rebuild the compressor? Are the gaskets or o-rings on both sides of the Valve Plate, included with this Kit? Are the Valve Plates available, if they need to be replaced? If so, what do they cost? I see that the Kit, #47, is out of stock until 5/15/2019. Do you see that the date as reliable? Can I order the parts, such that when they are in stock, they would be then shipped to me and charged to me at that time?
