Swap Fluid input/output

[Veaden]

Is there a mod that allows me to swap the sides of the inputs and outputs for fluids, in oil refineries chemical plants or electrolysis plants.

Thank you in advance

You can't arbitrarily swap input/outputs, the engine doesn't work that way. Mods can make recipes that re-order the ingredients/results so that different pipes are used, but where the outputs and inputs are is part of the entity prototype, which can't be changed without restarting the game.

https://mods.factorio.com/mod/GDIW is one that has alternate recipes which change the order of ingredients.
