HOT ENGINE START
12. Engine starting in extremely hot weather or with a very hot engine is sometimes
hampered by vapour formation in the fuel lines. The large thermal mass of the engine will
transfer heat energy to other metal components, including the fuel lines and the engine driven
fuel pump. The result is vaporization of fuel, which impedes the normal flow of liquid fuel during
a start attempt. The effects of fuel vaporization are most pronounced 15-30 minutes after
engine shutdown.
13. If significant fuel vapour is present in the fuel injection system, it can be advantageous to
pressurize the fuel system for a short period of time to circulate cooler fuel into the fuel system
and force any fuel vapour back to the RH fuel tank through the vapour return line. This process
is accomplished by setting the throttle FULL OPEN, setting the mixture to IDLE CUT OFF, and
setting the Auxiliary Fuel Pump to PRIME for approximately one minute prior to commencing
the start.
