I noticed the pressure gauge for my D.E. filter starting to leak air lately and want to replace it. However, after several trips to the local pool stores and hours of searching the viable option online, I have yet to find the suitable replacement part. I am hoping the experts on this forum can help me to identify the right type of pressure gauge (& assembly/air relief valve) for my D.E. filter. Any suggestion/advise are welcomed and very much appreciated.
My filter is Pac Fab Nautilus Stainless Steel 48sf D.E. Filter, but I am not sure about the manufactured date or model #. However, I know the filter was installed before 1995. I have also attached the picture of the pressure gauge below. Thanks again for your advice in advance.
