N/A FREEDOM/Aspen pump rebuild success

DO NOT SPAM THE SAME QUESTION OVER MULTIPLE THREADS
I just rebuilt my aspen .25, replaced almost every single oring/seal. 80% sure i assembled everything correctly per the assembly guide, however when I try to fill up the gun with the fill probe from an air tank, the air comes straight out the barrel end and the aspens pressure guage does not budge at all. I have rebuilt the rifle a few tile in the past and never had this issue.

Any feedback or suggestions would be much apreciated.
