my 2 choices for replacement pumps. Do you think second will work? 6.3 gallon?

That style gear pump the oil always flows around the outside of the gears. Vast majority of these pumps the rotation direction can be changed so arrow may or not be correct on an unknown used pump. Coming off the crank shaft I suspect you require a counterclockwise rotation pump as viewed looking at the pump drive shaft.
6 HP You could drive approximately 3.5 GPM at 2500 PSI

Not sure why they use the GPM because it can be misleading, but the 6.3 GPM one is the closest match to yours. It has just a tiny bit less displacement that the original one but probably not even noticeable during regular use of the loader.

So drove a couple hrs today to the nearest shop . They looked at it and said Its a mix bag. They thought it was a .16 ci and maybe a 2 gal at best. He explained again how the flow is figured but he lost me again.
They measured and remeasured again. and tried to match the pump to catalogue since the # are no good. Issue they had was if it was only a 2 gallon at best why does it have a 3/4 shaft. The mounting holes didn't measure up for size . They were also confused as to why it had same size port holes if it was a 3/4 shaft. Not that big a deal if I have to buy a new love joy coupler at 1/2 inch.
They were going to send it off some place to get their input.
