Has anyone done this before? I just filled my at44-10 .25 cal and it started to leak from where the fill probe goes into the tank.. i know I had put a male foster fitting on my sam yang 909s and deleted the fill probe for that airgun. Is it possible to do this to the hatsan? Anyone done this or know if its possible please let me know. Ive never had this airgun apart in the 5 years ive owned it. It's been a great air rifle and finally developed this leak. I only have the probe on this airgun out of all my lineup and would rather have a male foster if at all possible.
