I just received the subject pump which I purchased through EBAY. The pump has obviously never been used and came complete with the pressure gauge and overflow container (new). Unfortunately, the plastic air filter assembly was shipped attached to the pump and was broken in shipment. The plastic broke off flush with the pump so the first challenge is to get the plastic removed. Do you have a suggestion where I can get a replacement for this part or how I might replace it with some other suitable connector, diameter, thread size? I paid $100, shipping included, so I got a tremendous deal.
