1996 Gti Won't Run On Main Tank

[1996GTI]

I bought a used ski from a guy that said it ran great. When I picked it up it started right up. Took it to the lake a few days later started right up again gave it a little throttle and it died at the boat dock would not restart. I put new plugs in it, had full tank of gas, try start on reserve and main would not restart. I'm not a mechanic and I just purchased my first jet ski a couple months ago so I am definatly not and expert so this is all kind of new to me but I do have the shop manual and owners manual. I noticed the fuel filte didnt have any gas in it so I clean the element(very dirty), have spark, still dint start. Put some gas in the sparkplug hole ran for a few second an dthen died on main tank. Switch to reserve put gas in plug hole started and ran goog for a mintute or two switched to main tank and it dies. I can get it to run on reserve setting but if its on main it will not run. I have read a lot on this site about fuel line detioration(minestill has grey hoses) could this be my problem main line clogge in tank? Any ideas?

The longer you run it with the gray hoses, the worse the carbs will get. They deteriorate, into a glue like crud, and that crud sticks in the carb filters, and everything else.

Replace the gray hoses. (EFI hose is best). 4 buck a foot!

Clean out the Fuel Select valve.

Clean the filter on the bottom of the fuel baffle. This is the device on the top of the tank, with hoses coming off of it. It contains the fuel sending unit for the gas gauge.

Clean the filters in the carb (s), and now you will start to get her back running.

Really, I don't think there is much choice. The hoses must go!

Let us know when you get her going!

You have the same problem I have...Likely a corroded fuel selector. The part is actually cheap and I'll be replacing mine for next season.

It's called a fuel valve and they are $25.99

Take those apart and clean them up!

Might have to replace the O rings. But my hardware store has them!

Unless you have salt water IN them, and then you might have to replace.

Git rit o' dem gray hoses!

Just go to Auto Zone and get the black fuel lines for your seadoo. You will be wasting you money on exspensive injector or EFI fuel lines. Use regular Fuel lines. You will need about 15 feet. I think it costs like $.18 a foot here in Florida, at Auto Zone. They will last like 10 years before they fail again.

Where were you Karl, when I bought that 4 bux a foot stuff!!!

OK Ok, I guess I got a bit carried away!

After figgering out how intensely bad that gray stuff is, I over killed mine!

Thnks Karl.

sorry nate, but the 4 buck stuff is to withstand 45 psi of fuel pressure. totally unnecessary for seadoos. even injected ones only need i short piece from pump to engine.
