Sorry I was not trying to Polk fun at anyone it's just when I had my stroke my hands and fingers don't work like they should ... I need to find a pump that I can just bolt in place any help would be great I looked on eBay for one but could not find one with the right numbers on it I already tried 2 others from Ebay thinking they would work but no deal...one was way too big and the other would not read my setup .... Thank you Fred
