The Issue is, everything works correctly on both ends:
- GT6 Pipes only connect to things with Tanks (or other GT6 Pipes).
- The Fluid Importer only connects to things with Tanks.
- GT6 Fluid Pipes only have Tanks in the directions they connect to.
- The Fluid Importer does not have a Tank, so the Pipe wont connect.
- Therefore GT6 Fluid Pipes wont have a Tank on the Side the Importer points to, making it impossible for either of them to connect, meaning you need a Tank/Drum inbetween.
And then there is the second Issue:
- Some GT6 Machines have multiple Fluid Tank Outputs.
- Fluid Importer only takes the first Fluid to drain.
- If the first Fluid does not match, it wont try another.
So ofcourse you always will need a Drum or Barrel as inbetween to make sure shit works.
