    I recently acquired a pneumatic tank gauge which sports a glycerin filled gauge. There exists a small plug at the top of the gauge housing which I assume could be removed so that fluid could be added should the gauge require additional glycerin. Am I correct in my assumption about that plug and where would I find glycerin??

    TIA
