I have a hand pump thats about 2 months old. It was very dirty when I got it and it cut the oring that gives all the problems. I had a rebuild kit sent from sun optics and replaced all the orings in the pump after cleaning everthing up. Lubed everything just as Sun Optics said to do. I also have the orings I replaced even though they where not bad just incase I needed them later and the extra orings that came with the kit. The pump works fine and gives no problems. I have filled the gun 2 times since the rebuild. I have a tank now and have no need for it. Reduced to $100 plus shipping.
