7.13.2 Fuel Tank
Each wing is equipped with an integral fuel tank. The fuel line of each tank is equipped
with a removable coarse fuel filter. The fuel filler caps can be locked.
A drain valve is located at the lowest point of each fuel tank. Another drain valve is in
the gascolator located behind the firewall on the co-pilots side. All drain valves can be
easily operated.
A drainage cup is located on the inside of the baggage compartment door.
Fuel is supplied to the engine by an electrical fuel pump MAIN. When needed, an
electrical fuel pump AUX can also be switched on. Both fuel pumps are located in a
separated area beneath the cockpit ground floor on the co-pilots side.
Upstream the fuel pumps there is a combined filter and drain valve (gascolator)
installed. The electrical fuel pump AUX is controlled by a switch on the instrument panel
labeled
Fuel Pump AUX
.
It must be turned on during take-off and landing, when low
fuel pressure is suspected or during critical phases of flight.
Too low fuel pressure relative to the manifold pressure is detected by a pressure probe
at the fuel pressure regulator and another one at the airbox. The resulting fuel over
pressure is displayed as fuel pressure on the MVP-50P-AQ.
NOTE
When flying near the ground, such as during take-off and landing or if low fuel pressure
is indicated, the AUX fuel pump must be switched on in addition to the MAIN fuel pump.
The fuel tanks are vented via a vent line outlet located in the winglets.
7.13.3 Fuel Selector / Shut-Off Valve
The fuel selector is conveniently mounted on the control panel in full view of the pilots.
The red, arrow-shaped selector handle has a LEFT, RIGHT, and OFF-position. Each
position is notched and has a self-centering mechanism using a spring-loaded pin. The
selector handle points to the chosen position.
In both normal operating positions (LEFT/RIGHT), the fuel supply and corresponding
return line of the selected fuel tank are opened. The fuel supply and return line of the
other fuel tank are closed.
It is recommended to keep both tanks at approximately the same fuel level.
NOTE
Recommendation: Fuel tanks should be switched at least every 60 minutes.
