Hi, I got this mod the other day but I can't figure out how to use it. There are no new buttons on my HUD, the mentioned selection tool isn't anywhere to be seen (including the blueprints UI), and placing a pump jack does nothing. How do I use the mod?

You can find it on the shortcut bar: https://wiki.factorio.com/Shortcut_bar
See the animated gif on the github page for a practical demo: https://github.com/Xcone/factorio_pump

Ooooh, well snap. Thank you. I never thought it would be there lol. A whole bunch of mods have their buttons moved there. Cheers!

Thank you too. :-)
You made me realize I didn't really explain it very well in the description. Should be better now.
