Alternative fuels vehicle and fuel-system valve used therein

A valving system including a valve comprising

• a valve body comprising a housing having
• a first unvalved port,
• a second unvalved port,
• a through-flow channel extending between the first unvalved port and the second unvalved port, the through-flow channel providing continuous gaseous communication between the first unvalved port and the second unvalved port,
• a valved port, and
• a valving channel extending between the valved port and the through-flow channel, the valving channel providing valved gaseous communication between the valved port and the through-flow channel;
• a pressure release device in continuous gaseous communication with the valved port and integral with the valve body;
• and
• a flow controller having
• a valve element within the valving channel at a valve location, the valve element being rotatably disposed to rotate about a valve element axis of rotation and including a ball having a diametral passage therethrough disposed perpendicular to the valve element axis of rotation, and
• an externally accessible handle extending through the valve body and connected to the valve element, the handle being operable to rotate through an operating arc of no more than ½ turn to rotate the ball about the valve element axis of rotation between a closed position and an open position.

• a rotatable coupling at the valved port, the rotatable coupling permitting the valve body to rotate at least one full turn about the rotatable coupling, when the rotatable coupling is tightened to an external structure;
• a pressure release device in continuous gaseous communication with the valved port and integral with the valve body;
• and
• a flow controller having
• a valve element within the valving channel at a valve location, the valve element being rotatably disposed to rotate about a valve element axis of rotation and including a ball having a diametral passage therethrough disposed perpendicular to the valve element axis of rotation, and
