Do you know where the hydraulic reservoir is in your aircraft? If i remember correctly from my brief time in the PA44, its rear of the baggage door.

on another note, 1800 psi? Seriously? that is insane, you sure its not 180, or 18? 1800 is one hell of a explosion if something goes wrong. Not to mention requires one heck of stong compressor. Ever been near a scuba tanks or paintball hpa tank when they fail? lethal, and at the very least deafening.
