Is it possible to replace a braided hot water line on a Kohler, K-15160 Pull out spray Kitchen Sink Faucet? It is a one hole faucet. Cannot find any schematics online and was hoping to avoid buying another new faucet.

Does the faucet look like this one ? See the enclosed photo...

Yes, I believe it is 1/4" IP x 3/8" Comp. s.s. braided water supply line. You won't find it in Home Depot. Call Kohler at 1.800.456.4537 and buy it directly from them.

Yes it looks like that. I went to the Kohler website and they sell the whole head unit as one piece. I just want to be able to change one water line that has a pin hole leak in it

Chris, call Kohler. Talk to them in person. You cannot be forced to buy whole new faucet bcs of faulty water supply. I am sure Kohler will work with you.
