Computer-controlled auxiliary fuel tank system with multi-function monitoring system and user calibration capabilities

A device for monitoring the condition of a fuel system of a vehicle, comprising:

• a main fuel tank with a neck of other means of filling said main fuel tank,
• an auxiliary fuel tank with a neck of other means of filling said auxiliary fuel tank,
• an auxiliary fuel tank pump which pumps fuel from the auxiliary fuel tank into the main fuel tank of an automobile or truck,
• a sending unit,
• one or more check valves, and,
• one or more fuel lines to connect the auxiliary fuel tank and auxiliary fuel pump to a main fuel tank.
• a computer harness by which a computer-based fuel monitoring system (FMS) is attached to a vehicle, and,
• a computer control module which includes a Liquid Crystal Display (LCD) upon which can be displayed one or more characteristics of a fuel supply of a vehicle, and,
• the computer-based fuel monitoring system (FMS) which performs tests of both auxiliary and main OEM fuel supply systems and failures of both auxiliary and main OEM fuel supply systems in accordance with selected sequencing programs,
• where, the FMS is fully calibratable by the user of the, and,
• where the FMS is capable of performing one or more calculations based on monitoring the rise and fall of one fuel injector, and,
• where the user can calibrate the FMS to his/her particular vehicle without any additional programming, and,
• where, the FMS can function without depending upon or communicating with any on-board OEM computer, such that it is fully transparent to any on-board system, and
• where, for vehicles with a main fuel tank and at least one auxiliary fuel tank, the FMS monitors and measures the levels of fuel in both the OEM main tank and the auxiliary tank, causes to be transferred fuel from the auxiliary fuel tank to the main fuel tank such that the amounts of fuel in the main and auxiliary fuels tanks are approximately equal.

A method of monitoring a fuel system for a vehicle, comprising:

• a computer harness by which a computer-based fuel monitoring system (FMS) is attached to a vehicle, and,
• a computer control module which includes a Liquid Crystal Display (LCD) upon which can be displayed one or more performance characteristics of a vehicle, and,
• the computer-based fuel monitoring system (FMS) which performs tests of the main OEM fuel system and failures of the OEM fuel system in vehicles having only a main OEM fuel system, and both auxiliary and main OEM fuel supply systems and failures of both auxiliary and main OEM fuel supply systems in vehicles having both main OEM fuel systems and auxiliary fuel systems, in accordance with selected sequencing programs,
• where, the FMS is fully calibratable by the user of the, and,
• where the FMS is capable of performing one or more calculations based on monitoring the rise and fall of one fuel injector, and,
• where the user can calibrate the FMS to his/her particular vehicle without any additional programming, and,
• where, the FMS can function without depending upon or communicating with any on-board OEM computer, such that it is fully transparent to any on-board system.
