Oil/Fuel Lines

[jmartin915]

Somehow my marks disappeared from my hose clamps when replacing the lines so my lines are unlabeled...does anyone have a diagram or can explain where the lines go on a 717 GTI?

Thanks,
Jamie

To make this easy, they are marked on the top of the Fuel Baffle, and on the switch valve. To feed the motor, it runs through the water trap filter.

If you need more info, I have a complete description on it somewhere.

go from the filter to the bottom line on the carb and the return is the line on top, the line from the motor goes to the fuel pump on the side of the
carb (square block on the carb). usually it is "in the bottom and out the top".

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. Premium members get priority when it comes to getting quick detailed answers.

If you need pics, get the manual. Here is a verbal description:

well, now I just happen to have one just like that!

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!:ack

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?

I believe this diagram could help you verify the fuel hose routing.
