Describe the Bug

Using multiple fluid tanks on a train fill each one properly, but don't unload correctly. It works fine with 1 tank, but any more than that don't give full returns. The issue compounds for each tank over 1 being unloaded, as it seems to take fluid for each one at once, but only output fluid as if it was from 1 tank, aka the problem compounds with more tanks.

Reproduction Steps

1. Multiple Fluid tanks uncombined, mine is 10 2x1 tanks next to each other, totaling 144000mb.
2. Input tank of 160,000mb to verify content going in is correct. After filling it leaves 14000mb as expected
   3.output tank of 160,000mb, expect 144,000mb out, but got ~45000mb instead. Losses of about 70%
   ...

Expected Result

output of fluid will give less than input
