I cut the 3 screws + motor shank , make sure u mark ,IN and OUT , i use one MJ 1200, works fine, but will be better if u go 400 Gal. if u got the pump. I glue the access hole for shank propel + the small primer hole for pump. So NO more noise, NO more heat, NO more lube , much easy to ad the powder.
I make a test on that black plastic ( original that holding the motor) then find up the primer and glue, we use for PVC pipes, glue just well, i use temporary a MJ 1200 pump ( i got those around my stock) i run the pump inside the plastic container until i adding the powder then the return put right in my Berlin sock (sump) works PERFECT, no heat (i have to run a fan to cool down the motor) no more rust, no noise. Much easy to start , when u got the pump inside the main tank. I don't see , how to break down anymore, until u break the jar glass.lol
