Where do I tap into the system on my MF 50 to supply my front pump Im installing for my loader and where does the return line go?

Thanks

More info will help. What loader do you have? Pictures? Many older loaders, that had their own front pump, used the loader frame as the reservoir. On those the suction of the pump connected to a port near the bottom of the frame, sometimes next to the pump and sometimes via piping or hose. The pressurized oil from the pump goes to the loader control valve and the return from the valve goes back to the reservoir. Those do not connect to your tractor's oil reservoir.
 

I think its the MF 200 it has its own storage in the loader frame with an external filter. Its currently run off a rear pto pump but I need to free up the pto. Should I just plumb it into the loader tank itself? When I remove the loader Ill loose my oil flow through the front pump?

I have an MF 236 with a front pump. The loader has the reservoir in the frame similar to what you posted. The manual states that when dismounting the loader it is also necessary to dismount the front pump, leaving the hoses connected to the loader.
The two socket head screws are easily removed and the pump pulls off the shaft spline.
Although the manual does not address the issue of the shaft now rotating without any support at the end. I use a piece off 1 1/4" pvc pipe as a bearing/sleeve held in place with a plate bolted to one of the front bumper holes. This is on an MF175. The front pump requires removing the bumper/weight frame. I am not familiar with the MF 50 so this may not be necessary.
The parts book shows the hose routing.
 
Plumb into the loader tank and to remove the loader, just take out the two big pins where the loader arms pivot, remove
the pins at the top of the main lift cylinders and leave the frame attached, tie up the main cylinders to the frame and
the pump can stay too. You can disconnect and cap the lines to the loader cylinders on the inside of the right main arm
just up from the control valve. On ours, they both have a steel to hose junction there. You could swap the line
connection points over to quick disconnects if you're planning on doing it regularly. Way faster than taking off the
complete loader. Then with some kind of stand, you can drive in and out of the loader for the unhooking/hooking up.

Note..
When I had a loader on my MF 35...Case 610... I left the hydraulic pump in place, and added quick disconnects.
I then had HYD OIL pressure for a rubber tired cultivator as well as other implements...

To be clear to him, you fellows are talking disconnects on the lines to the cylinders not to the pump correct? The pump suction and pressure lines need to stay connected so there is oil from reservoir to pump, to valve, back to reservoir; or the pump must be removed or its drive disconnected. This allows use of the loader valve to control other hydraulic equipment, correct?

That loader valve will have a power-beyond port on it the you could plumb into for any auxiliaries at the back of the
tractor. That would leave the 3pt always available and the front pump will have much greater pressure and especially flow
than the internal lift pump.

I like the idea to leave the loader frame attached so the hydraulics can be used for remotes at the rear, see I knew I would get some great ideas here!

Thanks!
