Let me explain the fuel automation setup since it's pretty technical but super useful once you get it running right away you'll want to focus on three main components that work together: biofuel refiners fuel pipes and those biofuel tanks. The timing here is important because the refiners, both simple and advanced versions process raw materials at different rates so position them efficiently

Getting the layout right is crucial - your engines need that specific 3x2 grid placement with part hanging over water for optimal performance. When connecting everything make sure your fuel pipes create direct paths from refiners to tanks to engines since any breaks will stop the flow. The system's smart enough to prioritize active engines but you'll want multiple engines running if you're powering a larger build

Maybe interesting: watch your refiner placement relative to the tanks since shorter pipe runs mean faster fuel transfer rates. The advanced refiners process material 25% faster than simple ones so factor that into your setup timing. Once everything's connected properly, the automation takes over and you won't need to worry about manual refills anymore just keep an eye on your raw material supply to keep the refiners running

Keep in mind bigger rafts need more power so plan your engine count based on your build size and always leave room to expand the system later when you need more juice
