Praise God.

@Mlie thank you!

Updated to 1.5 - no changes necessary. Labelled as "1.5+" since the conditional .xml patching this mod uses is very safe and unlikely to cause problems on future versions.
Happy tugging!

@Stedi™
So, to summarize your advice:
"Learn to code"...?

BTW: You forgot to mention adding <li>1.4</li> and/or <li>1.5</li> to the <supportedVersions> tag in About.xml. Also, it is often not a simple or easy as you make it sound to update mods. Many mods will not function correctly in newer versions, either because it has a .DLL compiled with C# that is outdated and needs tweaking, or because a library it relies on is outdated, or because Tynan changed certain tags or other things that, likewise, needs to be changed in mods. And, often, it's not obvious what needs to be changed.

You can edit every mod in this game yourself in notepad. If it doesn't work for someone, just add the 1.4/1.5 folder and copy the lines containing the old versions in the existing files, paste and change, for example from 1.3 to 1.4, and save. If someone wants to play more with existing mods, open the files from the 1.4/1.5 folder with notepad and look for interesting phrases and lines of code to change.

Any chance of an update for 1.4 (...and maybe 1.5)?

Can anyone report on trying this in RimWorld 1.4?

I'll mouth polish ur wood if you update :D

update necessary?

Does this Mod work on V1.4 ? 'Gotta tug some GAS RAT TEATS for that sweet, sweet Chemfuel!

@Crack Rock Steady assuming you are referring to Combat Extended: I don't use that mod myself and can't tell you for sure, but I'm fairly confident that there should be no conflict with a mod with such a small scope as this one.

CE compatibility?

Updated!
(No changes were necessary; this mod would have been working just fine on all versions in the interim.)

It is essential that I reacquire the means to TUG THOSE GAS RAT TEATS in the V1.3 update. I hope that you consider updating that Mod soon!

@TurtleShroom Thank you very much! (and, no, in vanilla all that wet, wonderful chem is inaccessible - doesn't do anything but make the boomrat go boom.)

Holy crap, that name. Take my Award.

Also, Boom Rats DON'T make Chem-Fuel?

@SirDistic I believe it will remain chemfuel, but I would have to check Combat Extended to be sure. (It depends on if CE edits boomalopes to produce FSX, or if it replaces all chemfuel with FSX; I do not use CE, so I do not know.)

Will this turn to FSX in Combat Extended like Boomalops do or does it produce chemfuel? I'd prefer to made chemfuel.

BOOMRATS? I'm outraged! You promised me Boomdog or higher.
