risk of this is minimized by locating the line in a protected position during installation. modern installations also have a shutoff solenoid at the tank so that rupture will only release the fuel in the line rather than allowing fuel to come out of the tank. car manufacturers are using ultra-high-strength steel (uhss) to achieve the 5-star government crash rating. vehicles have uhss areas of the body structure like the a-pillar, b-pillar, rockers, side impact beams, and roof beams. this steel is difficult to cut with the standard extrication tools.
