AIRCRAFT OVERVIEW
The carburetor is of the fuel injection type with a separate idle cut-off device and is equipped with a
vapor return line that extends to the left fuel tank. The vapor vent line may become a fuel return line
if the needle valve in the vapor eliminator sticks in the open position. The left fuel tank should always
be used first to ensure availability of space for any returning fuel.
When changing tanks, don't stop the selector valve at an empty tank position, or at a
droppable tank position if no droppable tanks are equipped. Starving the engine of fuel
will result in engine failure. In such a case, perform the following steps immediately:
1. Turn the fuel selector to a loaded tank;
2. Make sure that the booster pump switch is ON;
3. As the engine takes hold, adjust the throttle setting as required.
Hydraulic System
The P-51D is equipped with two separate hydraulic systems. One is the main power system for the
operation of the landing gear and wing flaps. The other system is the foot pedal-operated brake
system. The only connection between the two systems is that they receive their supply of fluid from
the same reservoir in which a 3 cubic in. capacity cup is arranged so that in the event all the
hydraulic fluid from the main power system might be lost, the brakes may still be operated.
