I purchased a new unloader and installed but it still leaks. If I don't push the unloader all th way in it won't leak.When pushed all the way in it pushing the pin and opening unloader. I don't know what to next ?

Sorry that you replaced the unloader valve.
I suspect, from what you have written, that it's actually your CHECK VALVE that's the problem. Check out that page for details.
