1985 Ski-doo Formual Gas Tank Removal Question

Can anyone tell me how to remove the gas tank from a 1985 Ski-doo Formula? The rubber grommet on the fuel tank for the fuel pickup line became brittle and broke while trying to replace. The problem I'm having is that I can't get the new rubber grommet to press back into the hole in the tank (with the tank still in the sled).

I'm thinking I need to remove the tank and press the grommet in from a verticle position, but I'm not sure how to remove the tank.

Any tips on how to remove the tank or install the grommet will be greatly appreciated.

Thanks

ha i've had to deal with this one before. i managed to get that grommet in but it is a PAIN! try lubing it up with some oil.

otherwise, if you do want to remove the tank, it's pretty easy. take the seat off (two bolts under the tunnel) then take the bolts off for the tank. should come out!

I tried silicone and had zero success.

I'll try some oil in the morning... if that doesn't work... I guess I have to pull the tank.... snow is on the ground so I need to get it fixed in the morning... thanks for the reply

I've used grease and a dull standard screwdriver to help bush the stubborn side in.

try a little heat from a hair dryer it makes the rubber a little softer and easier to work with

Thank you for the replys. I ended up pulling the tank and installing the new grommet went smoothly. It's a good thing this actsaully happend. The pick up line in the tank was very brittle and ready to break and I'm sure it would have stranded me somewhere......LOL

I ended up installing a new filter, pickup line and fuel and primer lines.

I'm back in business, the sled is running better than ever and more snow is ion the forecast.

Thanks again.... Scorp80
