Ok so here's the long and short, I'm chasing gremlins! For some reason I'm not showing any fuel pressure on my gauge on my fuel rail to the carb. It used to work fine? So I thought maybe the gauge went bad, put a new gauge..... same thing?  Next thing I thought well maybe the pump is going bad? (All this time boat is running like normal) put a new electric pump on..... still no pressure? I've replaced all the fuel lines and filters. When I run a line from the pump just free into a can it flows great and doesn't appear to have any issues with flow or pressure?  Any thoughts.......
Thanks.

This is the fuel rail I'm running,  its your standard deal.  You can see in the pic were the gauge goes. I'm not running a regulator the pump is a marine carter limited at 6psi. Also I'm running a liquid filled holley gauge.

No it didn't die on me I was having issues with it loading up at idle,  so I looked at the fuel pressure to see were I was at and that's when I noticed it. Boat runs normal other than that.  I have replaced the gauge and blow thru the lines.

Yes, it does it after about 5 seconds of idling then you snap the throttle clear it out then it will be ok for a few then it comes back. It's dripping fuel from one of the secondary venturi . It does it periodically not all the time. I have adjusted the floats there good.

Ok that could be..... but why would my gauge not be reading the pressure?
