[Closed] Fox float rp2

Hi,
I have tried to adjust the sag on my Fox Float RP2 and failed ending up with no air at all
Is it because i have over-tightened the pump on the air valve? And damaged the pump chuck seal?
Have been trying to pump it up as the gauge is reading 0 but it's only getting to 50 and I can hear the air loss around the place where the valve is fitted and it comes down to 0 straight away. Can not remeber how the black rubber bit looked before but it is quite loose now. Do I need a new pump or is there something wrong with the air valve fitting. Help please...
Thank you
