A pump has crossed my mind. Been looking at the backpacker style hand pumps. Also have thought about
- a mini jack that fits under the front, ala formula 1, with the sliders on the bottom
- setup up an external tank with a syphon or pump to refill.
- a convoluted funnel that reaches back under the cupboards

This is all assuming I make a decision. Still going round in circles on three choices.

Stuck on travel waiting for a hardware team to finish so I can integrate some software, nothing but time to think right now.
