    fuel line diagram for 780?

    I just replaced the fuel float on my SLT 780. Now the ski runs great for about 10 minutes, then dies. It won't start up again for a few minutes, then starts and dies again after 2-3 minutes. Does anyone have a fuel line diagram for the sending unit? I think (hope) i may have hooked a line up wrong.

    Thanks!

    The sending unit has the connections cast into the plastic next to each of the nipples. You will have to clean it off well, and get a good flashlight on it to see them. WIll say things like Main, Res, Ret, Vent....

    After it stops running, open the fuel filler cap and see if any pressure is released. The tank should not hold pressure. Check that you have the OEM pressure relief valves properly installed.

    On my sending unit none of the factory stampings match any of the corresponding nipples. For example: The "main" stamping is in a blank spot on the sending unit.

    The "main" location is only used if your ski is set up with a reserve option. How many fuel nipples does your sender have on top? If 3, "res" is your main fuel connection point leaving vent and ret(urn)....
