Manifolds connected to fuel supply containers shall be supported to minimize vibration and shall be installed in a protected location or shielded to prevent damage from unsecured objects. A normally closed automatic shut-off valve that is held open by electrical current shall be installed in the outlet of the manifold and marked with the words "AUTOMATIC SHUT-OFF VALVE." The automatic shut-off valve shall be wired so that it shuts off when the ignition switch is in the "off" or "accessory" position and when engine vacuum or oil pressure is not present.
