Thanks! We just finished putting in new calipers, rotors, brake pads, brake hoses (front, rear, and rear upper), and anti rattling hardware. After all that we bled the brake lines and just when we thought we were done and had tightened down all the bleed screws we noticed a leak underneath. The male end of the rear upper brake hose was leaking when we pushed on the brakes. We didn't notice during the bleeding because the pressure was not building up but rather coming out the bleeder valves. Here is a video of the leak. You can see where the metallic looking drip is formed is the connection between the hose and the line (male hose to female line, the side of the hose closest to the rear):

I tightened the hose pretty hard down on with a 15mm line wrench, but didn't notice any other nuts to hold or tighten to secure this side of the hose. Any ideas on a potential fix?
We were rather suspicious that there might have been a leak somewhere when we were bleeding the lines because they would push out fluid when we stepped on the brakes, but then after a few seconds of not pushing on anything a lot of bubbles would flow out of the lines. We just carried on because we assumed that the bleeding hose wasn't airtight. This also adds complexity to the situation because the air bubbles flowed out of the front lines as well as the back on the same delay and the rear upper hose is only connected to the back. What could be the cause?
A couple things about our spider that we don't know are standard are that there are 2 brake fluid reservoirs right next to each other, one only goes to the front lines and the other only goes to the back lines. The second is that when we were pushing on the brakes to bleed them we could hear almost a breathing noise coming from the engine bay. When you pushed the pedal down it sounded like it sucked air in and when you let your foot off the pedal it sounded like it pushed air out. Is this another leak or just the brake pedal hardware doing its job?
