One day I cut open a yellow grapefruit and in the center was a seed that had sprouted in the fruit. The root was an inch long and the sprout was half an inch. That was over two years ago. The tree is about 3 inches in height now with lots of roots. It appears to have a tap root that is nearly 3 feet long! I want to transfer it to the ground but am unsure if it is safe to do so. I'm putting it in a larger pot with fresh soil for now. Can you give me any tips? I want this little miracle tree to thrive.
I think with a tap root that long, you better get it into the ground. If any inclement weather arrives, you can cover the top growth.
Here's an article that covers the general care needs of the tree: https://www.gardeningknowhow.com/edible/fruits/grapefruit/growing-grapefruit.htm
The phenomenon you experienced of fruit sprouting within fruit is called vivipary. Here's an article that explains it: https://www.gardeningknowhow.com/garden-how-to/propagation/seeds/what-is-vivipary.htm
I have two grapefruit trees that I grew from seed some 60 plus years ago. I live in NJ and the trees live outside during the summer and inside during the winter. One of the trees has leaves that recently start curling and falling off at a rapid rate. I cannot see any signs of infestation. Can you offer some advice? Thank you.
Wow! You've kept those trees a long time. Check out the environmental conditions noted in this article:
https://www.gardeningknowhow.com/edible/fruits/citrus/curling-citrus-leaves.htm The plant may need to be repotted in some fresh soil and perhaps in a pot that's a bit larger.
The skin is thick the meat is dry and tart. I have a Ruby Red on same watering and fertitization cycle those grapefruit are perfect. How can I fix this Oro Blanco issue?
Unfortunately, your photos did not come through. I could guess that it is one of two things, though.
It could be a lack of sulfur, potassium, and phosphorus, OR a pH imbalance. (Grapefruit are very sensitive to pH ranges that are too far out of where they should be.
It could be a sucker from the root stock, as well. If this is the case, it will originate from the ground, or at least below the graft point. The tree will be an entirely different species of citrus in this case.
My first guess would be the first set of problems.
Here are some articles that will help:

Notice skin, shape, meat that shows seeds and is tart and dry. Ruby Reds in same yard are amazingly good. I hope you see images, I uploaded 4.
I do see one image. This looks to be a lack of Sulfur, and in many cases a lack of Phosphorus and Potassium, too.

I planted a grapefruit tree several years ago, and it is just beginning to bear fruit. When I had septic tank issues, and it had to be dug to be pumped, I learned my tank is only about six feet from the grapefruit tree. Will bacteria from the septic tank's contents contaminate the fruit and cause the fruit to be inedible?
It is quite possible. Six feet is very close to the septic tank. Here is more information on the subject:

Why would my grapefruit on my tree turn prematurely yellow. Most of the fruit is green and growing nicely, but there are these occasional smaller ones that turn yellow
The tree will drop anything that it cannot support. If all of them were doing it, I would be concerned. In this case, this is a mild aborting of fruits.

ould it be have planted too deep? The plant is outdoors for the summer. It has rained a lot this summer, in the northeast.
This happens with pH swings, or really any environmental changes. They get quite particular about their surroundings. I would test and maintain the soil appropriately. These articles will help:
