Improving Diesel Water Pump to give more water

After Improvements on update 2.20.0, our game improved Newcomen Pump and Newcomen Kerosene Pump.
However, we forget another pump - Diesel Water Pump
This pump gives only 7 buckets of water, which is far less than the upgraded Newcomen pump.
This is a strange thing because there is more complicated process to make a diesel pump, but the result is much lower.
An advanced tool should be more effective.
Therefore, I hope we can improve diesel pump to get more water as well!
