Abstract:
1. A method for substantially minimizing the escape of fuel from a fuel tank upon penetration comprising: providing a fuel tank for a device, wherein the fuel tank comprises a tank wall and a fuel holding cavity defined by the tank wall; compressing a fuel-reactive rubber layer against the tank wall; and maintaining at least one of a first pressure, which is outside the fuel holding cavity and the tank wall, or a third pressure, which is within an interstitial cavity of the tank wall and outside of the fuel holding cavity, higher than a second pressure within the fuel holding cavity while maintaining the third pressure to be equal to or less than the first pressure so that a penetration of the tank wall will cause air to flow into the fuel holding cavity at a rate to substantially minimize the escape of fuel out of a hole created by penetration of the tank wall.
