How to automatically change liquid fuel in GlasWorks or in OilBurner buildings?

[aklesey1]

Factorio don't allows to mix fluids so one source of liquid fuel
What if i want use 2 liquid fuel? Or its not possible???

it is very difficult to achieve a situation where the factorio thinks that the pipe is completely empty and doesn't contain any liquid

So its very specific problem

you dont

since even you sinkhole/other void there will still be a part where you have 2 pomp with 2 fluids at the ends
although if you import fuel via trai if you wait for the glass works to burn all that is in them you can call a train with a different liquid , at least in theory
