Car is 2004 Grand Cherokee 4.7 liters. So I put new caliper in, fluid on the ground after mashing the brake pedal. Is there a trick to re-installing the brake hose to the caliper? I put new washers in, one washer on either side of the metal end of the brake hose. Too dark to look right now, but that is what I suspect. Is there a special way the hose gets attached to the caliper? Lastly, what about the torque setting for the big 9/16" nut that attaches the hose to the caliper? Is this a high number torque setting to properly crush those copper washers? I never did this job in this car before and if someone can offer me some suggestions, I'm all ears. Thanks very much, gentlemen.

Welcome to CF!

It is sometimes possible to get a bad piston seal directly from the supplier. In other words, a defective caliper. I had this happen last year with a complete 4-wheel kit from PowerStop. One rear caliper leaked the first time it was pressurized. Rockauto sent me a replacement overnight.

Check to make sure the banjo joint end is aligned with the 2 ribs so it is crushing the seal washer. There IS a torque setting for the banjo bolt, but IDK what it is. Just remember that bolt is hollow! Make sure there isn't a double washer on either side and the surfaces are clean and not scratched.

Take the wheel off, and have someone step on the brake and see where the fluid is actually coming from. But I just did 2 calipers. No special way. The front brake banjo bolt is 23 FT LBS though.

RGR: Retorqued it to 25 and it's fine. No more spots in the driveway

Nice, glad you got it figured out!
