i have set up a max size steel tank filled it with creosote and want to provide it via a fluid provider pipe at the bottom to an iron drum for testing, the drum is connected to a fluid supplier pipe and setup to request 2000 mb of creosote.
As you have seen, there is no fluid inside of the pipe at the bottom of the tank valve.

found the issue, the pipe needs to be connected to the basement of the glas to work.
