I made a little home-built hydraulics system and did a writeup on it. It is NOT very capable yet, but it's a bare bones demo with my rather jury-rigged choice of parts.

Could you print an entire hydraulic pump mechanism? At first glance, some types seem like they could work - I've got no experience with hydraulics, but some kind of tall gear pump would be my best bet from what I've seen so far.

Yeah, that or a peristaltic pump might get rid of the friction issues from using the syringe, possibly. They also would not need the check valves.
