randynavarro Posted December 10, 2009 Report Share Posted December 10, 2009 My glycerin-filled water pressure gauge has been outside in my van during this sub-freezing cold spell these last few days. Rather than "0 PSI", the guage now starts at "60 PSI." Will it return to zero in normal weather or do I need to get a new one? Quote Link to comment Share on other sites More sharing options...
