Fuel hose routing

[vilord]

I'm not sure if this is in the shop manual, if so just point me that way...

In the middle of the fuel tank is this big thing with 4 large hoses and a couple small ones coming out. I believe this is the pump/sensor/supply/return/vent etc hookup from the carbs to the tank.

One of the smaller lines coming out has a 3-way splitter on it with two lines connected, one left open.

Is any part of the fuel system supposed to be open to the air? This seems scary to me. I can send a picture tonight if it would help...

Thanks all!

It should be vented to the outside, not inside the seadoo. Do you have a seadoo shop manual? If not here’s an idea for you. You could join as a "premium member". As a premium member you can down load a authentic seadoo manual from the seadoo manual library. In the library is a variety of manuals for almost all years and models. You can view as many as you like on line as a PDF file, or download it and print it for your personal and private use. There are operator manuals and repair manuals for you to do your own repairs on your seadoo. The repair manuals have everything from troubleshooting, repair procedures to winterizing. It contains wire diagrams torque specs and pictures for disassemble and assemble instructions. In the spec sheets it tells everything needed to maintain oil changes, spark plug gaps, carburetor rebuilds and impeller wear ring tolerances. Click on the "Seadoo Manuals" link at the top of the page for more details. If you need any help or get in a jam, we are always here to answer your questions too.

Vent hosing should have check valves on the ends. It is okay to vent from the tank out - it is to prevent overpressurization of the tank when the fuel vapors expand in hot weather. But in general, no hose should be open without either a check valve or return line.
