Claim 0:
1. A tank valve system comprising:
a main valve body having a proximal end, a tank engagement portion, and an outlet connection portion, the main valve body being connectable to a neck of a fuel storage tank to thereby retain the proximal end in fluid communication with a fuel chamber within the fuel storage tank, the main valve body including a primary fuel channel and a shuttle interface channel,
an overfill protection device (OPD) including an overfill float element and an overfill shutoff valve, the overfill shutoff valve being housed within an overfill protection valve body, the OPD being configured to mate to the primary fuel channel to thereby position the overfill shutoff valve in fluid communication between the primary fuel channel and the fuel chamber, the overfill float element being movable between a release position and a shutoff position;
a gauge drive apparatus including a gauge float element, a shuttle element, and an extension body, the extension body being elongated along an extension axis, the gauge float element being movable with respect to the extension body between an uppermost position and a lowermost position, the shuttle element having a gauge actuation portion transportable within the shuttle interface channel between a top position and a bottom position; and
a fuel level indicator configured to indicate a high fuel level, a low fuel level, and intermediate fuel levels therebetween, the fuel level indicator being affixable to the main valve body and configured to magnetically communicate with the gauge actuation portion;
wherein
(a) the OPD and the gauge drive apparatus are configured to be within the fuel chamber when the main valve body is connected to the fuel storage tank;
(b) movement of the overfill float element to the shutoff position causes the overfill shutoff valve to prevent fluid from flowing from the primary fuel channel into the fuel storage tank,
(c) movement of the gauge float element from the uppermost position toward the lowermost position causes the gauge actuation portion to move from the bottom position toward the top position; and
(d) the extension body is attachable to the overfill protection valve body independently of the main valve body.
