Have a series 34 single handle Price Pfister kitchen faucet with side sprayer in the deck. I want to remove the hose to either clean or replace, but the quick connect will not come off no matter what I've tried so far. I tried putting silicone lubrication and letting it sit, and then following instructions I push up on the Quick Connect housing, then I push the plastic collet down while keeping up with pressure on the housing, and then try pulling it down and off but it would not budge. Any help would be greatly appreciated.
