You should contact Klaus Witte at Top Hydraulics in Oregon. He talked me through my hydraulics problems. I had the typical problem with the chafed wire that finally broke. I accidentally sliced through one of the hydraulic lines with a razor knife while cutting off the tape around the wires and lines so I ended up having to buy a replacement line from Klaus. He helped me find the broken wire and fixed me up with the correct parts. There are some videos online that he put out about the 370Z system. You can look at all the parts and how they should look on his videos.
