I am working on getting the parts to install my boost and FP gauge. I ordered the two fittings for my boost gauge (NAPA) and have seen the pics of how to hook up FP but just wanted to know if some one had part numbers or size of fittings to hook up a FP gauge. I went to NAPA and told them what I was doing and asked for help and they told me they did not have what I needed!! I know they do or they can order them so I wanted to just go in with the part #'s or sizes I needed. (Fittings, needle valve, hoses etc.) Thanks in advance. BTW some of this info is sinking in because a buddy just bought a CTD JUST LIKE MINE , and I have been able to answer all his questions so far!
