Yep I gotta mop the brake fluid off my floor every day.
Or is it the transmission fluid?
Or the oil?

If you design the pump properly the high pressure circuit is contained within the low pressure circuit. I think a decent seal can contain 30-60 PSI.

Now if you are talking about a beat to snot Bobcat with 7500 hours on it, that is about the same as a 65 Lincoln with 600,000 miles and no maintenance.
