Sorry if the start of the thread was lost somewhere. Quick summary: The problem was the engine twice ran for some time and then died and would not start. When I checked the Racor later, it was half full of fuel so diagnosis was either electric fuel pump not working, plugged pickup tube or vacuum leak somewhere so it could not pull fuel from tank. I have been chasing those down and now confident the pump and pickup are working, and vacuum leak is either in fuel line or Racor holder. That is why I decided to replace fuel lines when several listers suggested that as most likely culprit (from past experience with the same problem). Dave
