This is not a question, more of a statement of my own experience with my Merc 115 efi 4-stroke. This may help someone in the future.

Engine was running real rough and spewing fuel from the air intake and after doing all the usual checks including fuel pipes, fuel filters, plugs, pin coils, injectors and air filter I came across the above post which mentioned fuel pressure regulator vacuum hose. Of course the fuel pressure regulator is inside the fuel supply module which has 8 bolts holding it together. I carefully took the module apart and found to my relief that the vacuum hose had a 1 inch split along its length. One new hose later and she fired up perfectly without missing a beat!!
Just a simple fix, it's a pity that the hose isn't more accessible
