Ok, thanks guys.I see there is a problem with that holder.I forgot to say i brought a new regulator,that's when i saw that the plastic holder broke, i installed it any way.
Well this is my second chance at trying to repair it, the first epoxy didn't work, so i went to work and got some airplane 5 min epoxy (you know the type we use to hold the wings on when there is a problem right at departure

). So let see if it works this time.
