WARNING
The fuel caps are the non-vented type. Failure to properly secure the caps will result in fuel
leakage and unequal fuel feed between the two tanks during flight.
An engine fuel primer is located on the instrument panel to facilitate starting Turn the knob to
release the plunger then pump the desired amount.
WARNING
After using the primer, insure that the knob is locked in place to
prevent Additional fuel from entering the engine cylinders.
The 7KCAB only, is fuel injected and has additional provisions for limited inverted flight. See
Figure 6-5. This includes an engine driven fuel pump and Van electric boost pump, which is
used for starting and for emergency use should the engine driven pump fail. The switch is
located on the electrical panel. A direct reading fuel pressure gauge is, installed in the
instrument panel.
A 1.5 gallon header tank is mounted aft of the firewall. A standpipe in the tank allows .75
gallons to be used for inverted flight which is approximately 2-3 minutes depending on
power settings. During positive G conditions, the tank automatically refills by gravity from
the main wing tanks.
WARNING
Continuous inverted flight is limited to 2 minutes. Approximately 3.5 minutes of flight under
positive G conditions is required to completely refill the header tank. Temporary fuel starvation
may result during an extended series for aerobatic manoeuvres involving a majority of negative
G conditions.
NOTE
Should fuel starvation result during inverted flight, return to positive
G conditions. The engine will restart within 10 seconds.
HEATING AND VENTILATION
Heat is obtained from a heat muff attached to the engine exhaust manifold, Both the front and
rear seat control knobs are located on the lower left side of the instrument panel. The front seat
heat outlet is on the left side of the firewall and the rear seat outlet is mounted to the cabin floor
between the two seats.
Fresh air is obtained by two rotatable air scoops on both sides of the cabin forward of the pilot.
Adjust the scoop forward for fresh air intake and rearward for air exhaust.
Additional fresh air vents are located in the left and right wing roots. Air flow is adjusted by
rotating the valve as desired.
