overtightened a psi gauge when replacing it on the sand filter and now have a hairline crack in the plastic housing right above the thread part. The crack becomes noticeable only when you screw in the Psi gauge sensor? What to use to seal the hairline crack? gorilla glue Or JB plastic weld would work? Links to the best product would be great.

That is unfortunate. Bad thing is there really is no reliable way to repair a crack on the pressure side (filter). Anything you apply to the crack on the outside could very easily get pushed outwards. Screwing in the gauge will only work to spread the crack open again. Keep in mind those filters contain quite a bit of pressure as well, so safety first. If you do try, be mindful of further cracking or rupture, and don't be too disappointed if you have to replace the entire valve assembly. If you're doing to try a patch, probably JB Weld from Walmart would be a decent choice.

Lowes have so many variety but proabbaly the JB WaterWeld Would make the most sense. Any tricks to apply this stuff? I have never used this stuff before. Thank you.

I use JB Weld all the time - steel and plastic versions. They are very easy to use. Usually 50/50 mix and apply. They also have convenient syringe-type packages for easy dispensing. You can get it a Lowe's, HD, Walmart, etc.
