A computer controlled auxiliary fuel tank system provides one or more additional fuel sources as either original equipment with new vehicles, or as an aftermarket addition to an older vehicle. The auxiliary system monitors and controls the on-board testing of each main fuel system, and their associated fuel displays, whether or not the vehicle includes a main fuel computer system. On-board testing is compliant with California Air Resources Board, On Board Diagnostics II, and with the Environmental Protection Agency On Board Diagnostics II) requirements. The auxiliary fuel system comprises an auxiliary fuel tank, having an auxiliary fuel pump, a sending unit, check valves, inlet and outlet fuel lines, a wiring harness, a computer module, an auxiliary emissions canister assembly, vehicle installation means, and LCD and LED display devices. Fuel levels in each tank are read, compared and balanced once every 4 seconds. Prior to each readings, the tank's senders are pulse-preconditioned so as to reduce the errors associated with fuel additive corrosion. In addition to the display of the gallons of fuel in each system, the vehicle's gas gauges are rescaled so as to indicate the percentage of total fuel on-board. In addition to warning of fuel quantity problems, the operator is made aware of the potential causes of such problems by being provided with a series of diagnostic trouble codes resulting from testing.
