You guys got me thinking.I have an old compressor,vintage 1956.2 stage 80 gal.tank.works very good,but it is getting slow,to build up pressure.At 49 years old I guess that is to be expected.I have been toying with the idea of buying a new one,but maybe I will price a new pump.I contacted the co.that made it and parts are no longer available for it.Champion Compressor Co.
