Fuel System Check / Cleaning
If the fuel tanks are contaminated with dirt (check the inside by using a
torch), they must be dismantled (fuselage tanks only) and cleaned. For this,
drain the complete system (by using the electrical fuel pump) and dismantle
all connections. Clean the tanks by using fuel or spirit / alcohol. Do not use
water or solvents.

mount junctions (hanging up)
2. main gear beam where connected to the fuselage
3. nose- / tailwheel where connected to the fuselage

For towing (forward only), connect the rope to the main gear.
