Since crosman is going to replace ur pump find out who you spoke to and get their email address and send them pictures of the first tube and the so called "new tube" sent to you as a replacement. Sun optics is contracted by crosman to build and supply the pumps, I high doubt crosman will be happy with sun optics clearly sending you a replacement tube that is defective in the exact same way as the tube on the pump..*(&^ tell crosman ur sending the tube sun optics sent you with the pump back to them so they can see with their own eyes.I will be honest dude ur the first person I've seen with type of issue and I am not at all pleased with sun optics. I mean how hard is it for the person you spoke to over there to walk into the warehouse and pull a tube, open the package and make sure its in top notch condition.
