Hello everyone in the know concerning this pcp. I've got a friend that's had this pcp for a little while and it's developed a leak. The last time that he filled it, it leaked down over night leaving it empty, we're wanting to know that if there's anyone that's still working on them? Some years ago, our dear friend Wil Piatt was the guru and master that replaced the seals in my CA 707 and I was very pleased at the work that he's done for me. If there's anyone out there that can help us with this problem, we would greatly appreciate it. TIA
