From what I noticed, the seal for the pump needs a decent amount of force to seal well, so I would add a decent amount of holes in delrin with a coarser thread to prevent stripping.
Those in the pic were chrome plated aluminum with chromed steel brackets, essentially copies of the Polarflo TT conversion kit for the D4 pump. The machining of these are pretty difficult...
