The loader had to have its own reservoir because the donor tractor had no factory hydraulics. Use that reservoir. Doing it this way completely divorces both hydraulic systems on the new tractor. That is not a bad thing.
I am afraid that I am missing something here because this solution seems so obvious and shouldn't be a source of confusion.
Provided that all four cylinders on the loader are double acting (two ports per cylinder) you could run both systems from the W-400 reservoir. Near the bottom left side of the W-400 reservoir is a drain plug. Put a Tee there and pipe both supply and return into it. Size the tee to be the same size as the supply port on front pump. Supply hose goes to pump. Return hose goes to reservoir port on fender valve.
That drain plug port is only 3/8" but that will be big enough because the only flow through the port will be the displacement volume of the chrome piston rods when they sre moving.
I made an error on a previous post. The W-400 CAN accomodate three valves. You could run the loader functions and the rear remote with only the IH hydraulics. That means you will have to buy a bunch of salvage parts.
When you get to the point where you want power steering, you will be going to the salvage yard. That might be a good time to price out the parts you will need to convert everything to IH if that is something you want to do later. IH power steering can't use the existing valves that are attached to the cast manifold above the reservoir. The PS valves look similar but are different.
I'd like to see a picture of the front mounted pump driveshaft and crankshaft coupling. I'm in the process of mounting a front pump on my W-400.

Today's Featured Article - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
