Question 3

Form the LP Cock, fuel passes to an engine driven LP Fuel Pump which
serves two purposes:
 A. To boost pressure of the fuel to prevent cavitation of the HP
pump.

Answer 3

LP FUEL PUMP/ Low Pressure Fuel Pump

Question 4

To reduce the possibility of low temperatures forming ice, fuel heating is applied. Fuel heating is achieved by passing the fuel through a form of radiator which uses hot air (or hot oil) to control and maintain
fuel temperature above freezing.

Answer 4

FUEL/AIR HEAT EXCHANGER

Question 5

Its purpose is to prevent foreign particles from entering the engine fuel system.

Answer 5

LP FUEL FILTER/ Low Pressure Fuel Filter

Question 6

Not withstanding this, (?) will be incorporated to ensure that the fuel supply, albeit possibly
contaminated is still available.
