After purchasing a borked pump and deciding its not worth the $20 to fight the guy on a return I decided to take it into my own hands to perform an upgrade.
This here pump housing is made to be a DIRECT bolt up using all existing parts including the pump seal.

Things to consider:
The pump housing and lid do need to be printed with supports. For the housing be mindful of the support overhang. I did 80 and it didn't print enough supports on the discharge port. You can see in the video it came out weird looking due to it warping and separating from the supports before it could print fully.
Supports aren't terribly hard to remove from the overhang in the pump housing but if you can change dense support layers or separation distance in your slicer you can ease removal.
