Liberty LW-6 backhoe. How many gonna pump do I need

[Chrisb62]

Sorry for title typo. Should says gpm.

I've bought an old lw6 backhoe. It doesn't have the pto pump anymore as the guy I bought it off just had it running right from his tractor. It still has the built in reservoir.
I'm trying to find out what size pto pump I would need to run it. I've heard 8 or so. Other have said upwards of 20gpm.

Thanks

It looks like this. I'm hoping maybe someone with something similar could tell me what PTO pump they use

I would say 8 to 14 gpm 2200 psi will work, From what I came across searching the web
