Also, the lower tank trim was tricky. The maint manual didn't help with this. There are metal L-tabs that hook the trim. You can see the tabs on the side of the tanks. The front of the trim is attached with a rubber grommet. The back with a 4mm bolt. Annnd, there's Velcro in the middle!
Unbolt the back, pop out the front, pop the upper middle 'velcro', then you have to slide the piece down to disengage the tab. I bent one side trying to figure it out, but was able to bend the tab back.
