3d custom pump kit for Apollo?

Looking into getting this thing... but after doing a little searching on my own, I decided to go to coop's link in the description of this video:https://youtu.be/S5WFC3yngGQ

But alas, the only thing that displays upon following the link is the stock piece. Can anyone link me to the Pump part of this kit? I cant find it.

Thanks, and cheers,
