View attachment 3821604 Hello Now it´s time to get ready engine for 1st start. Im not really sure how oil pressure need to connect, and not want to broke nice supercharger. Im sure that oil pressure is connect to that fittin middle of the picture. there pressure is shared to bottom bearing and that bearing where I install tube. What about those two ones? I have markt left side Z fitting and highest fitting needs also something. Do you have any better picture of info M-39 , M-40 supercarger tube locations? I have try to google pictures, brochure,... but for example those Hot Rod magazine McCulloch supercharger engine articles (part 1 and part 2) have nice pics but took so that not see how tubes are located.
