Doesn't help describe what you did. What lines were disconnected? From the tractor, from the valve block, from the cylinder? It makes isolating a problem difficult as you are only giving comments. Like saying it's wet out. Are you standing in the rain or a river? Just saying your comments are not specific enough for a remote diagnosis.
DMW this was a reply to another question witch was asked I can't get both comments in this bracket so I will start over for you.
When I disconnect the hoses from the control block at the backhoe witch is approximately 18 inches from my quick disconnects or maybe 20". The lines were replaced 2 years 33.4 hours ago with new lines and couplers, The hydraulic fluid coming from the pump when the hose is in the upright position on what would be considered the drivers side "In American and Canadian countries sitting in the drivers seat facing the front bucket" the hydraulic fluid resembles what would be considered to be a fountain like sight approximately 4 to 5 feet in the air. Now when I install the hose on what would be considered the drivers side and remove the coupler from the passengers side and place the hose in an upright position it does the same thing so my assumption is there isn't any restriction in the control block for the back hoe but maybe a diversion in the block somehow.
