Order and parts (SROEXT 5000)

I currently have a replacement impellor on order for my bubble master pump. Order # #100000772 that is still in a processing status. (Made the order friday evening) I would like to see if I can upgrade my shipping and also discuss adding additional items to the order that are not listed on the site. E.g. Non siphen tube, basically at the PVC parts that exit the gate valve. What number can I call?
