Replacing a pressure gauge on a Waterway Crystal Water cartridge filter.

[Sand-D]

We have a waterway 325sq ft Crystal Water cartridge filter that was given to us and we need to replace the pressure gauge. The one in there is busted corroded and useless. The whole assembly costs about $50 and we only need to replace the gauge and waterway doesn’t seem to sell just the gauge for that assembly. It is a back mount and we measured the inner diameter of the housing where it screws in and it’s 2 inches, so we need to get a gauge (I’m assuming) that is 1-1/2 inch in order to fit inside that casing. Also the plug/screw on the back is (we think 1/4 NPT) We looked for a 1-1/2 inch diameter gauge on Amazon with 1/4 inch NPT and all we can find is 1/8 inch with 1/4 inch adapter that screw onto it. Any advise or information on this is much appreciated.

I replaced the whole part. No way to get the darn thing apart.
