I've had some recent issues come up with my engine that I've worked through for the last couple of months as I've had time. I finally worked it all out. Found several small issues that resulted in some somewhat bizarre symptoms. Anyway, I put everything back together and second guessed my hose locations. I have the service manual for this thing, but it doesn't just lay it out in a diagram which hose goes where for each and every one. The ones in question are the ones that connect to the upper and lower bearing vent nipples. I know that they go to the vapor pump, but not sure which goes to which pump nipple and/or air box. Does anybody have or know where I can find an actual diagram for this, or have one yourself?

Not sure what year your motor is, but for my '98 Johnny 150EXECD, Page 2-52 (the last page of the fuel system has a diagram) of the recirculation system.

The upper and lower bearings are connected to the vapor pump. The hose from the vapor pump directly connects to the lower main bearing. The hose from the vapor pump connects via a tee to the air silencer and the upper main bearing.

It's a 94'. I'll look on that page when I get home tonight. I could've just missed it.

Correct, but I was trying to figure out which goes to the inlet/outlet of the pump. I can only assume that the center nipple on the pump is the inlet and the one on the front upper side is the outlet, but that's where I'm kind-of hung up. That would make sense as far as how gravity works anyway, pulling from the lower bearing and pushing it back to the top of the block/air box to vent.

I just looked up your model number and the 150EXECD and 150GLERV are similar, but the differences that I see are the differences I have found in mine! I think I just found the main source of my confusion. I think that my powerhead was replaced sometime prior to me with a newer one and even the guy I bought it from didn't know, or maybe he did lol.

Follow up...
I connected the hoses in the configuration you described and my fuel starvation issue went away on the muffs. I haven't lake tested yet, but the simple fact that it was still happening repeatedly on muffs before I made this change and now it's not seems to be pretty solid evidence that was my issue. Thank you for chiming in! Now to figure out which powerhead is on this thing...lol
