Sounds like it's his supplier. They are rebuilt pumps. Stevenson gets them from xman. He'll be using my video. He's had "the failure rate is in single percents but still way higher than I would like to see". So less than 10%. Mines the only one that's failed this fast. Probably a result of my " stage 9000". But I'm the only one whose dissasembled it.Yeah i know some people here or in FB groups who have the Stevenson CP3 kit which is the same as the Xman CP3 kit or they brought it from Xman and is working fine so far... at least more than 5,000 miles.
