Need tips on droping a Demon gas tank

If it's the model in your avatar, you can probably just loosen it to get the filler neck out. If you need to pull it, remove the sender wire, ground strap, and fuel hose from the sender. remove the filler neck screws. Put a jack under the tank without trapping the straps. Remove one strap, then loosen and remove the other. Carefully lower the tank. It helps to have two people if there is fuel in the tank as it will slosh and slip off the jack. Hopefully the tank is just about empty or it can be a bear to handle. I like to spray plenty of WD40 or lube around the filler neck grommet to help keep it undamaged.
Have fun!
