I have my pumps set up like this, and it'll only seem to work if I manually remove and replace a pump along there, does 8L train mod, or FARL interfere with yours?
its really weird, I can get it to load/unload with pipes or pumps when I place them manually, but the moment the train leaves, and then returns, nothing happens. I'm pretty sure it's some sort of weird update mechanic.
Edit:

edit2:

this is what it does whenever I place something next to the pipes or pumps. once this happens they unload no problem, but only then.
