Full Flex Diesel Cracking (1X)

Runs all three Cracking recipes that output Diesel in the same Cracking Unit. Input Heavy Oil, Naphtha, Fuel Gas, Hydrogen and Oxygen in any combination, obviously it can only do the cracking if the relevant pair of ingredients are available, but it won't be blocked by presence or absence of other ingredients.

Uses "Fluid Tank" sorting for output, and a very precise set of Pipe Balancers with "Enforce strictly even inputs" ticked to ensure correct ratios are input. Do not plug any other pipes into these balancers.

You may loop the Fuel Gas back in, it's not required, in the screenshot I use a ghost pipe to show how it be connected.

IMPORTANT:

In order to work correctly, the Cracking Unit MUST be set to "Trucks CAN IMPORT cargo".

The Cracking Unit SHOULD be placed in a truckless LOGISTIC ZONE that serves no purpose but to PREVENT TRUCK DELIVERY.

Truck Import being enabled enlarges the internal buffer sizes to 40 units, and this is required for stability. Unless you are already using a logistic zone over the area, you just paint a logistic zone and move on, no configuration of it is required. (If you are using a logistic zone, I believe you'd need to make a cutout as logistic zones seem to stack in a permissive way, if any logistic zone allows delivery to the building, delivery will be allowed).
