How to install new test cocks for FEBCO 765

Both test cocks on my Febco 765 1 in. PVB Backflow Preventer broke (just some thread left) and I need to replace it. I found the replacements in our local store but I cant find any recommendations how to install it. Do I need to tighten it hard with tool or just by hand, do I need to use the tape (looks like the original did not use any)?

Another question is : I am not sure for how long it was broken but ports was fully opened since that (not like 45 degree as recommended). Do I need to do any clean up inside of preventer.
