My 5050 keeps spitting hydraulic fluid out of the vent cap that is located by the PTO lever.I replaced the hydraulic pump filter thinking it was plugged, but no help. Anyone have any ideas on why this is happening? Thanks!

Could be a few things. Vent cap not venting properly, air getting into the system somewhere causing some cavitation, and once the air pocket gets purged back to the tank, causes things to spew out. Possible hose collapsing internally causing a restriction issue...
