Describe the bug
Infinite amounts of any liquid can be obtained when flowing fluid is adjacent to a fluid pipe with any liquid.

To Reproduce
Steps to reproduce the behavior:

1. Place a cyclic fluid extractor on a liquid barrel (or another fluid storage block) filled with water (or any other fluid)
2. Place a single fluid pipe next to the fluid extractor
3. Place a fluid source so that it flows into a block adjacent to the fluid pipe.
4. The flowing fluid next to the fluid pipe will turn into a source block, quickly draining the pipe of its contents.

Expected behavior
The fluid pipe should not interact with adjacent fluids.

Additional context
I tested this in an instance with only cyclic installed, and the same behavior was present; however, cyclic 1.12.2 is no longer supported, so reporting this on the cyclic github would likely not lead to a fix.
