I believe the L has a relief build into the hyd. block so hopefully everything is ok as long as it wasn't run too long.You have three ports, one from pump that went to loader,
one coming back from loader going back to the tank and the
one coming from the loader that is the power beyond feeding the rear three point.
The pump port must be connected to the one going to the three point so you have hydraulics and do not deadhead the pump, originally before the accessory block with the threaded ports was put on there was a plate with custom orings on it connecting the correct ports and blocking the unneeded one. You either need that plate or a hose connecting the 2 ports. Just hope you have not blown your pump as you have no relief valve in line now.

A full on deadhead on the pump would most likely result in a noticeable result be it noise or fluid.
