Claim 3:
4. The fuel system of claim 2, wherein the at least one processor is further configured to:
determine if the primary pressure value is greater than the first upper pressure threshold value after the first switch from the primary fuel to the secondary fuel; and
perform a second switch from the secondary fuel to the primary fuel if the primary pressure value is greater than the first upper pressure threshold value, the operating speed value of the prime mover is greater than the fuel type initialization speed threshold value for the prime mover, the absolute speed error value is lesser than the steady-state absolute speed error threshold value for the prime mover, and the fuel switchover timer threshold duration from the previous fuel switching event has elapsed, wherein, to perform the second switch, the at least one processor is configured to transmit a third control signal to open the at least one primary valve, and a fourth control signal to close the at least one secondary valve.
