This winter, when I took all the Tupperware off and did a lot of cleaning and checked wiring systems that needed positioning, I decided to try a little insulation on the fuel tank.
I used a couple layers of duct tape, covered by a layer of metal reflective tape and covered pretty much all of the fuel tank. I did not have a fuel odor issue before, but I thought that this may offer a little more insurance. My tank is now insulated a little more.
