Mine is a 2004 Friendship 41'. The pump is located in the middle of the compartment forward of out fresh water tank, behind the water heater. I had to pump in the left side slides once. The handle for the manual jack should be 5/8" outside diameter, though 1/2" will work. Turn the silver knurled knob 2 turns CCW to allow the manual pump to work. Ours is "newer", so turning the small slotted screws for each oil circuit then opens the electric solenoid valves, one for each motion.
Our unknown issues were three electric interlocks preventing normal operation of pump and valves:
- Driver's seat fully forward
- Battery condition (probably voltage)
- Park brake set
Knowing this, and after lubrication of moving parts below with spray silicone, everything works great.
