With the fuel inlet valve open, the fuel pump continues pumping fuel into the fuel bowl, where the resulting excess fuel causes the fuel-air ratio to become lower than nine to one, which is then too rich for ...
This imposes limitations on the amount of fuel carried and the order in which fuel must be used. Turbine engines burn fuel faster than reciprocating engines do. Because fuel needs to be injected in to a combustor, the injection system of a turbine aircraft must provide fuel at higher pressure and flow compared to that for a piston engine aircraft.

One shuts off fuel pumps when fuel output pressure is low, to prevent them from heating (since they rely on the fuel itself for cooling). The other enriches the nitrogen levels in the air in the fuel tank, so there is insufficient oxygen there for ...
