I have 2 of the military surplus Davey 15 cfm Compressors I feel are ready to be parted out. Both are diesel and the engines run fine. In both cases the auto drain systems quit, so I plumbed them to drain manually, and over time it appears this is not enough to keep them clean. Is anyone interested in the parts or complete that knows more about them than me and can either fix them or use the parts? ph: 701-667-1312 or scubaone@scubaone.com.
