The description of the parts package on your website did not appear to be in proper (size) scale However, after following a Youtube video, I was then able to decipher what parts went where to be sure I was ordering the correct parts that I needed. Parts were shipped promptly and I found that replacing just the check valve o rings and sea ts, it cured the problem without having to use the other parts that came with the kit package. Would definitely order from this site again. BL NC
