HELP - PS Pressure Hose on Pump Side

How do I get this thing off? I am using an 18mm flare wrench after soaking in pb blaster. It appears to have a smaller fitting that goes into a larger one. Can I remove the larger one from the pump and separate them on a vice? Any tips to get them off on the car?

I got it loose at the rack side - I thought that was going to be the hard part...

I have it apart in the driveway now - Really need it tomorrow. Any help would be appreciated.

Thank You!

I ended up using a 1" wrench on the fitting with the 18mm flare on the smaller one. The fitting on the brand new pump broke loose. It is all back together now.
