Revision:
-
A gasoline can and a funnel with a flexible end may be used to fill the fuel tank or a device
described below may be constructed. It consists of a gasoline can and tire-pump. A gasoline can
funnel is set on the gasoline can - a tire valve is brazed on the funnel and a hose on the tire-pump
(compressor) is connected to the valve. A suction tube with a filter is welded to the gasoline can
funnel. The tube is inserted into the gasoline can. A flexible hose is attached to the funnel.
Pressure in the gasoline can will increase during pumping. Gasoline is then forced through the
hose into the fuel tank. An advantage of fueling with this device is easy handling by 1 person.
Close the fuel tank filler using the lockable cap when the tank filled up.
Clean the aircraft surface if stained with gasoline.
CAUTION
It is highly recommended to pour gasoline through a filter if it was not tested for water content.
After fueling, allow 20 min. for water to settle out on the bottom. Drain off some fuel and look for
water.
Avoid getting gasoline on the rear cockpit canopy which will run the the perspex canopy!!!
4.5.4.4 Fuel emptying
Precaution
Use the same precautions as during fueling.
Draining procedure
1. Connect the airplane to the ground
2. Open the main fuel valve
3. Fully extend the flaps
4. Put an empty gas can under the drainage hose (on the bottom of fuselage close to the right
hand flap root)
5. Open the drain valve (under the right wing fillet, close to the right hand flap root)
6. Close the drain valve when desired quantity of fuel is reached
7. Close the main fuel valve
8. Retract the flaps
NOTE
Remove the fuel tank filler cap to speed up draining.
