For those who are not aware, on a typical self contained hydraulic jack,
the outer round tube is *not* the outside of the hydraulic cylinder, it
is a fluid tank that is coaxial to the cylinder. This is not true for
units where the pump is separate from the cylinder and connected by a
hose.

Through that rubber ditty up near the top?? If so, how would one get oil

there???

Yep, the rubber "ditty" (I call them hole plugsG). Use a nozzled bottle,
and squirt it into the hole.

('tis messy when you overfill, too! Make sure the ram's DOWN on the last
fillup)
