DO NOT put any tank liner in your tank. I clean rusty gas tank with pool acid. I pour about half a gallon in and shake the tank for about 10 min. Then add same amount of water and shake it again. Before you dump it out add a bunch of baking soda to neutralize it. Then add Hot water and flush a few more times. When you're done get a hot air gun or a hair dryer to dry it out. Then I spray WD-40 all over in the tank and it looks like new
That fuel gauge wire connector is a bear to get at and to disconnect. Very sharp looking scooter.

I know it's been a while. You need to reline that tank. The liner is breaking up and getting into your filter/carb.
