ABSTRACT:
A fuel tank switching apparatus provides for the automatic switching of fuel delivery systems from a tank or tanks containing fuel which is taxed, to an auxiliary tank which stores untaxed fuel therein. The apparatus is particularly adapted for use in large, over the road diesel powered semi trucks, but may be adapted to other types of motor vehicles as well. The apparatus automatically transfers fuel delivery and return to the auxiliary fuel tank whenever the parking brake is applied, which action will only occur when the truck or vehicle is parked, or possibly in very rare emergency situations. As both the parking brake annunciator (light or audible device) and the pneumatic pressure system are independent of the primary service brake system in large vehicles, the apparatus receives a signal from the parking brake system to switch tanks automatically with no intervention required or allowed by the driver or operator. The system may also provide for automatic switching back to the main fuel system, and notification to the vehicle operator, in the event the auxiliary fuel system is depleted.
