7. DESCRIPTION OF THE AIRPLANE AND ITS SYSTEMS
The auxiliary fuel tank is located in the fuselage, aft of the passenger compartment and underneath the baggage compartment floor, on the right hand side of the main fuel tank.
Fuel is gravity fed from the auxiliary tank to the electric transfer pump, which is used to pump fuel from the auxiliary fuel tank to the main fuel tank.  From the pump, fuel flows through a check valve and into the top of the main fuel tank.  The check valve is installed between the auxiliary tank and the main tank to prevent siphoning of fuel from the main tank back into the auxiliary tank. The only ports in the auxiliary fuel system are the auxiliary tank outlet and drain. All auxiliary fuel system components are grounded to each other and the external ground stud, located under the trailing edge of the left wing.
