Hey all!

It's been a while since I've posted here but I just realized I need to add a pressure gauge to my filter. We bought the house 2 years ago and it did not have a gauge on it. The Multi-Valve Port has a sight glass and just above that to the right has a black plastic bolt that looks like it could be removed and replaced with a pressure gauge. I'm just wondering if that's where it's supposed to go or if that is something else. There's also a threaded piece on top of the filter that looks like might possible be important, too. Should the gauge go on the Multi-Valve Port or the actual filter? I can take pictures later on if that would help, but wasn't sure if this is "common knowledge" for smarter people than me.
