2002 Buick Lesabre 6 cyl Front Wheel Drive Automatic 90k miles

I put a radiator preassure test on my car and I found a leak on a little black elbow looking thing that is above the water pump. I can't determine if it's a waterpump gasket, the black elbow, or something directly behind the top side of the waterpump.

Those little black elbows do leak. You need to see if you can spot the source with a small mirror. Dry the entire area off and retest it to see if you can spot it, remove some basic stuff if that is what it takes to find the problem

There are two of those elbows on the vehicle. Plan on replacing both of them at the same time.
