you should be able to buy the tool at the autoparts store. it should have 2 ends on it. cant remember which one for ours. as for the gas tank, you may not have to remove it, unless you already did. when you try to start it, she turns over yes? but just doesnt wanna catch? you can try changing our fuel filter, which you are already doing, dry out the charcoal canister, may have to buy a new one but probably not, and run a couple bottles of DRYGAS in your tank. It is normally used to remove moisture but if you dont have that much water in your tank, could help out.
