TY for comment, all fixed, No mods are required.

Good Design and Idea.

The blueprint is surely only functional with mods, right? If so, you should add that to the description. Don't be surprised, I tested without mods...

During testing, I noticed that a cable is missing in the heavy oil production line, which causes a refinery and a pump to fail.

I also noticed that the regular fuel doesn't actually flow through the line between the fuel mixer and the rocket fuel mixer.
