I have a related question to the Vacuum hose connection on the fuel pressure regulator for a Mercruiser 5.0 EFI engine from 1999. I found the vacuum hose disconnect laying in the bilge. This hose is connected on one end to the fuel pressure regulator and I'm trying to find where to reconnect the other end? I don't see any port on the flame arrestor for this as it says on the fuel diagram. Anyone can help me on this basic question?
