Would it be possible to add the Rocket fuel item back? Maybe add a recipe to turn liquid Rocket fuel into an item. Because i wanted to use it as a Fuel for trains.

Sorry, there is no rocket fuel item in Lunar Landings. I don't want to re-add the item just for one purpose. Pretend that you've never played vanilla and had no expectation of a train fuel in between solid fuel and nuclear fuel :)

ok, i made a mod for myself to add it back in. Thx for the reply. :)

to be fair, jetpack would be another purpose :P

Yeah that too...

You can use solid fuel and nuclear fuel in the jetpack too.
