I may not be understanding what you are saying correctly, but a Tee fitting in the line will not work.  The Belarus hyd system is open center, meaning that oil circulates constantly.  You would have to cut the line from the pump to the control valve, braze or clamp fittings on each end, then run the flow from the epump through the new valve then back to the old valve through the new fitting on the cut line.   You also need a valve with a Power Beyond capability.   If you Tee into the line, oil will just go to the path of least resistance, and nothing will happen.

you have a different setup than me.  I have the same pump but the spool valves are up in the dash panel.  I have the square block with o'ring face that attaches to the pump (pressure side) and has a hard line that goes up to the spool valve with a large banjo fitting.  I can get a new hard line with the block/o'ring and banjo fitting for $80.  Was thinking about getting one and then cutting it and installing a compression T fitting midway up the line if I can find a T fitting for that outer line diameter.  Don't think that'll be a problem.  For return I will run a line from the joy stick valve body to a port (o'ring boss fitting) on the top of the tank that  empties into the hydraulic filter.  Would be super simple as I can use hydraulic hose for that.

Yeah so you unbolt the fitting off the pump and fabricate/weld a fitting on that is common so you can easily run it to your loader valve block then hook it back into the tractor hydraulics wear the oil would flow from the pump normally.  Now it just goes through you loader valves 1st then to the tractor hydraulics.   I took some pics but they are not the best.  This guy did it too but not sure what he did regarding return back to the factory hydraulics spool valve.   Mine was simple just tied into the pump pressure line.  So I basically use them loader valves all the time even when the loader is off as they work better then the old factory spool valves.  The factory spool valve handle's location is inconvenient to use vs a handy joy stick in a comfy spot. I got so annoyed with them that I rigged up a different handle for the 3pt hitch handle to make it easier to use.

Yes that's the way to do it, guys hook into the pressure line off the pump.  I'll post a pic of my 825.

Adding additional hydraulics on 825
« Reply #1 on: December 13, 2017, 02:47:33 PM »
Bought an 825. Want to add a joy stick control for the loader.  I have a three point blower so I need one rear
Hydraulic to run the chute.  I don't want to switch hoses to run one of the bucket controls. And I prefer joysticks for loader controls.  So I have to add another pressure line off the pump to provide for the joystick.  Originally I was going to install a line with a banjo fitting and mount banjo to banjo on the valve body where the pressure line from pulp attaches to the valve body.  But I can't find a double banjo fitting that is big enough for that size banjo fitting. I think it's 30mm.  So I am considering buying a new pressure line and cutting it and adding a T in that line to branch off to my joystick. Anybody done this?  If so how did you do it. Thanks
