1. A system comprising:
a fuel supply line configurable to transport gaseous fuel at a wellsite;
an engine of an equipment coupled to the fuel supply line, the engine configurable to perform a wellsite operation at the wellsite using gaseous fuel received from the fuel supply line;
a reserve fuel tank configurable to store gaseous fuel diverted from the fuel supply line, the reserve fuel tank comprising:
a first valve configurable to couple a first end of the reserve fuel tank to the fuel supply line to divert gaseous fuel from the fuel supply line into the reserve fuel tank; and
a second valve configurable to couple a second end of the reserve fuel tank to the engine, the second valve being positionable in (i) a closed position to prevent the stored gaseous fuel in the reserve fuel tank from transferring to the engine and (ii) an open position to transfer the stored gaseous fuel from the reserve fuel tank to the engine; and
a control system configurable to adjust the second valve from the closed position to the open position in response to detecting that a pressure of the fuel supply line is lower than a predetermined threshold, and wherein the control system is further configurable to adjust the second valve from the open position to the closed position in response to detecting that the pressure of the fuel supply line is above the predetermined threshold.
