So I got new counters and faucets. Unfortunately, the old faucet had an extender on the supply lines that the new one does not, additionally, it doesn't appear to something i can swap from old to new. Due to this, the water supply lines are too short to reach the new sink. What is the best way to handle this?
Old sink connector
New sink connector
The broken supply line appears to be integral to the shutoff valve. You will need to replace the valve with something like this
You may wish to consider replacing both of them and installing new flexible supply lines.
According to your tests, the supply line is certainly the culprit. Are these new replacements? If not, do replace them with new. If so, then one is faulty. Either way, sounds like the answer is the line between the valve and the faucet.

You typically use braided steel supply lines to connect the sink to your supply.
You can get anything from a few inches long to a couple feet long.
