Joining two faucet supply lines

[tate16t]

I have a Kohler kitchen faucet. It has 3/8” supply hoses running from the faucet under the sink, one looks like this....

...and the other looks the same except it has a smaller connector leading to the faucet.

I need a long 40 inch hoses since the existing hot line is leaking. The current 20” hot line hose is connected to another 20” supply host in order to extend it. Its leaking at the extension. I’m think one 40” hose would be better.

What is the connector size I require? I know one end is the 3/8” connector end but what sizes are the other ends?

Thank you

The same. The other. A smaller connector running to the faucet. You are not describing things well.

You can pick up a fitting like this and add a standard faucet connector to it.

Or these supply lines.
