Shouldn't the LNG Boost Pump be before the main LNG Pump? My understanding is that the boost pump is there to prevent cavitation in the main pump.

I believe in this case, the boost pump is to raise the pressure of the portion of the LNG used in the pre-burner since this is necessarily higher than the pressure needed for the fuel going into the MCC. If that is the correct interpretation, it would be after the main LNG pump.
