My k-10416 has never worked right. The sprayer didn't work so I replace the diverter valve. That fixed the sprayer but now the faucet leaks from just under the bonnet. What do I do. Do I replace all the o-rings?

My Kohler kitchen faucet K-10416 has never worked right. First the sprayer never worked so I replaced 75878 and then the sprayer worked. But the faucet now leaks from just under the bonnet. Do I need to replace all the O-rings?
