Fuel fill check
The fuel pump logic includes a fuel fill check function.
When the fuel pump is running, the fuel level must increase with 4 % within the fuel fill check
timer. This timer is adjusted in 6550 Fuel pump logic, but the level of increase cannot be
changed. If the fuel level does not increase at least 4 % within the adjusted delay time, then the
fuel pump relay will deactivate, and a fuel fill alarm occurs.
