I'm have added a spool valve for a top and tilt and am down to the final hose routing/building. Need to find a route for the valve "Tank" return.

Choices seem to be running from the rear to the front fitting on the FEL control or, to that same steel line, but where it dumps into the tank.

Either way, I'd like to know and have on hand the type of fittings I might need.

I'd like to know the type of fitting, and size on this item: "75595-63410, Plug, Orifice"? It threads into the FEL valve body tank return (FEL TL421). This elbow threads into it "75550-61900, Elbow adjustable" or "75540-61910, Elbow, adjustable" Those thread into it using an O ring, with a backup washer and nut. I take that to be an SAE ORB.

The end at the tank (much shorter new hose needed, but tighter to work on) uses the same steel return line as above and goes into the tank using Adapter 75582-66810.

Knowing what any or all of those are will help me figure out the way to go.

I've also thought about removing the line and having a shop cut it and add fittings as needed. My understanding is the pressure is so low compression fittings or even hose clams are good enough.


I guess I can just break down and disassemble it and take it to the hydraulic shop, as I have to get hoses made up anyway.

Assume nothing - take the fittings out and have the hose shop ID them.

Tank return pressures should be a few hundred PSI max. When properly installed hydraulic compression fittings are good to thousands of PSI. Hose clamps a little less :rolleyes:
