The problem is defiantly with the 2.0 body. I had to just run just the flat part of the zip tie sticking out no fuel tubing and no end on the zip tie, and sometimes in a hard crash it still open the tank. It happens when the truck slides upside down it pulls the tank open. There is a fix to this problem where you add throttle linkage stops to the end of the springs on the tank lid. This helps but it can still open. It will make the lid close better as the springs are now stiffer with this mod. I hope that makes sense.
