Not sure how much info you have on the plumbing but make sure you have oil. I have a Sanden from a Ford 302 on mine and was not told about it from the PO and almost smoked it. If you go on the Front Range forum and search on board air there is some good info and online to. I am sure you know this but just throwing it out there. If your not running a tank may want to think about it. So you dont have to run the compressor all the time. I have a 5 gal tank and when it worked it was great. nice start. good luck.
