Pull-down faucet hose doesn't slide into sink/counter holes
Sadly, it is often cheaper to just buy a new faucet....if you decide to go the repair route, try to identify the brand and model of your faucet by going to the manufacturer's web site.
This is why I always advise to keep the faucet box for future reference on make and model. Parts are then much easier to identify with parts explosion diagrams from the manufacturer. Good luck!
