The Dual Fuel Tank Transfer function enables the transfer of fuel from a secondary fuel tank into a primary fuel tank for dual tank equipped vehicles. Outputs available include the transfer pump, control solenoid and transfer light. Inputs available include the main tank level, secondary tank level and a transfer request switch.
