Power Gear

I have a Gulf Stream Tourmaster with Power Gear leveling system. The Hydraulic lines are connected at the top of the motor/pump housing reservoir and they are leaking more than I would like (no leak is best).
I have never worked on hydraulics and have some questions. Do the fittings have o-rings that can be replaced? I envision they are machined fit and the fittings would need replaced. If they are o-rings, and I loosen them, will I need to be concerned about loosing fluid and bleeding air after the seals are replaced? If so , how to bleed? I expect with the jacks fully up the fluid would be mostly in the reservoir and I would loose little other than air.

I've rebuilt one, but am not exactly recalling the type of fittings used?
My foggy brain says they are banjo fittings, with a hollow thru bolt and hard metal washers, but I could be wrong.

There's basically no fluid and no pressure when the jacks are retracted. You can easily take the hoses off and reseal them.

The system is self bleeding, run the jacks up and down a few times and it's done.

If your Power Gear unit is like this one, all you have to do is snug the flared hose fittings!

Make sure you place a wrench on the 90 degree elbows before tightening the hose fittings. There are no rubber O rings to make the seal. Metal to metal contact under the right torque seals the joint. If the 90 degree elbows are leaking where they are threaded into the manifold they may have to be removed, coated in pipe dope or apply Teflon Tape and re-install. If they are flared fittings like the hose ends they may only require tightening.
