Still though, since you only change the fuel capacity, why not use a patch?
It would also increase compatibility with other mods by quite a huge margine, here is the code to do so:


* Save it in an XML file
* put the XML file in the folder "Patches", and the "Patches" folder should be in the same folder as "About", but NOT in the "about folder" and don't but "patches" in any of the "1.1" "1.0" or "1.2"
* Then just delete the version folders - They are not at all neded, since all you actually do is change fuel capacity anyways..., and DONE.

If ever the game updates to v1.3 all you, more or less, needs to update, is the supported versions in the about.xml file...

what you have now is... well, not that compatible if another mod comes along to change it in some way.
The design of this mod, means that is should load as close to Core as possible, not last.

Using a patch, you can load it when ever, however, and is save game compatible too.
