Send it back, as $60 is a pretty steep price for what appears to be a POS. You find instruments clusters for the Task Force trucks all the time on ebay for a lot less than that that should have a usable unit in it. Keep in mind that the original capillary units did not have much that could mechanically malfunction.
There actually was an original oil gauge out there last week on ebay that did not sell, and although I cannot recall its starting price at the moment, it sure was a lot less than $60. Also check with one of our stovebolters, Steve "JIMBO59CHEVY" Giminiani. I have had very good luck with parts from him. Also consider the Parts forum on this site.
Good luck,
