Well tank/plumbing replacement

[Douglas D]

Hello,
Replacing the plumbing from the well pump to the pressure tank in a 1969 home. Trying to figure out what all this is and if I need it all. There is what looks to be a boiler drain, temp gauge, and a PROVECTR air bleeder valve which was part of the original system. DO I need all of this ?
Thank you for your help!

No you don't need the hose bibb. I don't know what that large part is below the hose bibb? Pretty straight forward. Water comes in the black pipes and out the blue pipes. Doesn't look like a lot of extra to me.
