Black Diamond 782 seal replacement help

I need to replace the seal on my Black Diamond as it was leaking from the area where the CO2 cart sits. I have the parts and have the gun mostly disassembled, but can't seem to get the guts (I think its called the valve assembly) out of the body tube. Looking at the EVP, I am trying to remove the parts from 782A002 to 782-019 (they all assemble inside the body tube). I have everything else removed, except 781-054. Any advice or help would be appreciate as this is the gun I have set up for my kids to shoot.

Thank you.

God bless,
Michael V.
