Here is a verbal run through:
There are labels on the fuel selector valve, and on top of the Fuel Baffle.
first, I assume that you have removed all the gray fuel lines, and done a proper burial for them? (that is 6' deep, and pack the dirt back over the spot, and then pee on it!)
Then, get new black ones. I am an overkill kind of guy, so I replaced the vent lines too. And, I got the 3.99 a foot stuff for EFI cars. That comes to about 100 bucks to replace the fuel line! (gasp!)
Fuel path is like this:
Starting at the VENT hose, on the side of the sea doo, there is a check valve, that only allows air to enter. then go in to the T fitting, where the line intersects with a line coming from just in front of the seat, where there is a little rubber plug. These lines have to be open to flow.
Back down to the T, then it goes down into the baffle, and inside the top of the tank.
Now, FUEL enters the bottom of the baffle, and goes through a screen. This is a little plastic screen, that collects GOOP from those gray fuel lines, and saves it for the day that it can shut you down, when you are far away from the boat launch site. Fuel then goes up the baffle, (through the RUN side, which is about 2" up off the bottom of the tank) and goes to the top of baffle, to the fuel select valve, where it intersects the hose from the RESERVE side, DEPENDING on the fuel select valve. (The reserve side comes from about 1/2" off the bottom of the tank, and up to here) Then, the fuel goes to the water trap, which is accessed through the trunk, behind the fire put out device. Otherwise known as a fire extinguisher. The fuel goes through this water trap and screen filter, then back to the engine through the MAIN FUEL FEED LINE. At the engine, it enters the pump, and is pressurized to just the right pressure, to keep the engine fed at any RPM. Then, extra fuel goes back to the tank through a fuel return line, and in the top of the baffle.
INSIDE the carb, in enters from the pump, which is activated by pulses from the crankcase, and goes through the LAST filter. This guy is usually clogged up. There are pics of it all over this forum. JPX posted a good pic of it recently. Gotta clean this little filter all the way.
So, you had a breakdown in the fuel system somewhere?
