Anyone have a source for parts for older PE GCs for which PE itself no longer has parts? Specifically, my company has a GC in Latin America with malfunctioning injection port temperature control. I don't have model number at my fingertips, but could obtain that. Any help would be appreciated.

Try contacting a Company like Analytical Maintenance Services out of Boca Raton FL 561-750-8541. That company comes into contact with older style GC's and parts on a regular basis.
