What kind of pump is it?

The stock IH distributor drive pump will not fit an M made before 1950 unless you swap out the front engine cover and the timing gears.

M&W made a similar pump that fits the older tractors, but they're rare and hard to find.

Plumbing is easy. You need the pump, a reservoir, and OPEN CENTER control valve with pressure relief. Many people use the stock belly pump for a reservoir, others add an external tank.

Basic plumbing:
1. Run a hose from the pressure OUT of the pump to the IN on the valve.
2. Run a hose from the OUT on the valve to the IN on the reservoir. This is usually near the top of the tank, and would be the fill pipe on a belly pump.
3. Run a hose from the OUT on the tank to the suction IN of the pump.
4. Run hoses from the two work ports on the valve to quick-disconnect hydraulic couplers, often called "Pioneer couplers" at the rear of the tractor.

That's it. Basic instructions to plumb up a single two-way remote valve...
