Answer: I can't tell without looking at the fluid. It could be escaping from the fruit, as a result of insects feeding on the fruit or it could simply be sap from another part of the tree. I would pick one of the fruits and dissect it, looking closely for holes in the rind and in the fruit itself. Or take one of the affected fruits to your local cooperative extension office for microscopic examination. Wish I had more suggestions!
