I'm not completely familiar with the ESS kits, but supercharger installs in general usually have a one way valve/check valve that gets installed in the tank vent hose. This prevents boost pressure from pressurizing the fuel tank. If your kit has this as well, you may make sure that it is oriented properly in the tank vent hose. In the AA kit it's installed under the plenum, but again, I'm unfamiliar with your kits installation.
