4) If gasket is not torn apart, you can probably seal it again using rectoseal on both sides of washer. This is how I fix problems. Buy rectorseal from home center.

Your fuel petcock has a filter on it that should not be affected by the gasket. If the gasket is paper and will deteriorate and cause problems , by all means get it out. If it is just a round plastic circle the size of a quarter it will not affect anything sitting in the tank. If you decide to retrieve the gasket , drain the tank, take the tank off, turn it over , and remove the fuel tank sender and you should get good access to the interior of the tank. If there is a splash of gas left in the tank it will help you wash the item to a position where you can see it and reach it with a long grabber or tweezers . Please NO SMOKING during this procedure.

This is referred to as a SPUD gasket and should be readily available at a Lowes or a Home Depot.

Yes, it seems the folks who wrote the instructions have never actually done any plumbing.

first place a rubber washer on the bolt, then put it through the hole in the tank. Then place another rubber washer on the bolt, followed by a metal washer and a nut. Tighten the nut, not the bolt.
Using a screwdriver hold the bolt in place, and tighten the nut until snug and the rubber washers are compressed slightly.

Follow this step with all the "tank to bowl" bolts.

Now the bolts are tight to the tank and will not leak water.

Then place the large rubber gasket over the flush valve hole on the bottom of the tank. and set the tank on the bowl with the bolts through the bowls holes.

Place a metal washer on the bolt, and then a nut.

Tighten each nut equally until the tank has no wobble.

you only need one

yes to do it the right way you should take the tank out of the car empty and rinse out then replace when completly dry

never have used a torque wrench to install toilet tanks. Put gasket on tank and insert bolts with rubbers washers through gasket and set tank on bowl in a level and straight postion and start nuts tightening them evenly until tank starts to snug to bowl. Hand tight is usually sufficient, you will see the rubber gasket and washers will compress to bowl and tank forming a seal (EVENLY) and tank will be firm to bowl. DO NOT superman torque these nuts! Compare the torque to finger strength on a wing nut. Hope this helps ,"if I understood the question."
