Your hydraulic unit looks like ours on our 2016 Outlaw.
I've had to go through our system a while back, I did not find an accumulator to store pressure, nor do I see one on your system (that is where stored pressure would come from).
It looks to be the Lippert Leveling System, (LCI).
The fluid flow depends upon the valves opened electronically, they have built in electro magnets (solenoids) to shift the valve open, so I believe the jacks would stay in the up position until a valve opens, (they do have manual over-rides that takes an allen wrench turning in a set screw to hold the valve open).
It's all controlled by a main controller, I call the brain, lol.
I cannot tell from the pictures where the leak is from, are you sure a line didn't pop a leak?
It has been a good while, look through the archives on jacking systems, I wrote up how my system operates fairly thoroughly in discussion with Judge, when he was having a problem about the same time after I did. I have a background in Hydraulics, but am retired from it all now, sorry I don't have a link for the info at hand.
But, I did find this in my notes:
Leveling operation function notes.
*The motor and the pump always run in a counter-clockwise direction, looking at it from the end of the motor with the reservoir in the rear.
*Whether extending or retracting the jacks, each jack's particular solenoid operated cartridge valve, needs to be open.
*When extending the jacks, an additional function happens electronically, and a signal triggers the solenoid operated, internal directional valve, directing the flow to the blind end of the cylinder(s) involved, via a black hydraulic line through each selected & opened cartridge valve controlling said cylinder jack(s).
*Manual extension of the jacks can only be performed from the control panel, located within the cabin, with power on, and the parking brake set, possibly needing the engine running if a low voltage error occurs.
*The leveling, and jack cylinder extensions, cease their operation when the ECM (electronic control module) senses being at the right height, from pre-programmed signal of the level sensors.
*One possible reason, for the level system hydraulics to fail, is if the circuit breaker trips power outage to the motor.
*The circuit breakers are located inside the battery compartment, under the step lid, (listen for the electric motor to be running on the hydraulic unit, and familiarize yourself to this during normal working conditions).
*The hydraulic operation, in normal no electric power (or turned off), is that each solenoid controlled cartridge valve, per cylinder jack, is in a closed (normal no-flow) position, and the pump manifold solenoid directional valve aligned to allow the flow to return to tank from the blind end of each jack cylinder (black hyd hoses atop the manifold connections), and conversely the flow would travel to the rod end of each jack cylinder when the pump is actuated in CCW direction, via the orange hydraulic hoses connected at the tee, on the side of the manifold.
*Automatic, powered jack retracting ceases, when the pressure switch sends a signal to the ECM of the system, essentially telling it's at full retract, or an obstruction prevented full retract, (always visually inspect for full retract).
*Automatic retract is supposed to happen if the vehicle's parking brake is released, or the ECM loses that signal it is applied.
*Whenever retracting the jacks in a manual over-ride condition: Open the cartridge valve with a 5/32” allen wrench to the cylinder involved, remove plug on end of motor, run pump motor in a CCW direction using a ½” socket on a drill motor, when finished; return the plug on the motor end and cartridge settings to their closed set screw positioning.
