Fuel storage

[chillholm]

Hi ,


Hope I'm using the right forum for this.

Put the 99 gtx LTD under wraps for the winter in Melbourne Australia and I have an almost full tank of fuel. Read through the Seadoo manual ( Chapter entitiled ' STORAGE') and not once does it mention to completely drain the fuel system. Have put some octane boost in to keep the levels at the right amount so fuel doesn't go bad.
Every body I have spoken to says that I should be draining the fuel tank completely, some say leave about 10% fuel in the tank etc, etc .etc..
Who should I believe?? I mean if the Seadoo manual has no suggestion of completely draining the fuel tank, why are others so insistent in saying I should drain the tank?

REMEMBER AS THE GREAT DIRTY HARRY SAID...AND I QUOTE....

" OPINIONS ARE LIKE A**HOLES. EVERYBODY'S GOT ONE!"

Any help on this would be greatly appreciated. Cheers.

according to the manual it says to have 1/2 a tank......good practice would be to store it with "Stable" to preserve your gas. You are also supposed to turn the fuel valve to off while running it to drain the fuel out of the hoses and carbs.....according to the manual I have

This is a good topic because I have heard arguments for both ways now.

Full or not full.

Drain the hoses and carbs. Don't drain the hoses and carbs.

Arguments I have heard.

Full - the fuel will expand when the temperature increases and pressure will build and fuel will over flow out the pressure relief vavles and all over your seadoo, etc. This happened to me this winter due to a faulty check valve on my vent line. It came out the vent inlet and spilled down both sides of my seadoo and started dissolving my decals. Thank goodness I smelled it early on and took care of it.

Not full - leaves room for condensation. Which is made even worse with ethanol in the gas.

Drain the hoses and carbs. - Keeps the varnish down and carbs and line from gumming up.

Not draining the hoses and carbs. The seals and rubber bladders, etc. in the carbs do not get dry, stiff and crack and tear prematurely.

With all this mixed information, it is hard to know what you should do.

True but I pulled my info out of the shop manual.....seadoo sells lube spray that you ingest into the air box. I am sure you could do the same for long storage by spraying it in the fuel feed line to the carbs.
