Lost Pin/Plunger on PSI Gauge

I was replacing the air relief valve on my DE filter and needed to remove the filter's pressure gauge (link below). Upon taking it to the garage to apply some teflon tape to the threads prior to reinstalling, I seem to have lost the little metal plunger that sits on top. Is this a problem? Gauge reads the same pressure as before I removed it.

Thanks Allen. Does the gauge need to be removed or can I assess whether it's reading zero with the pump off?
I may just order a new one, but it's only 3 months old.

I read your post as saying the gauge was removed. Same goes if the pump is off. Gauge should read 0.

Thanks again. I noticed the pin was missing after I reinstalled the gauge. It's reading zero with the.pump off so I think I'm good, but I may grab a new one anyway.
