1. Locate the connection between the fuel cap fitting and routed through the fuselage to the left
wing.
2. Remove the fuel cap.
3. Place an air hose nozzle inside the fuel cap fitting and close to the vent line.
4. Squeeze a couple of short bursts of air through the vent adapter into the vent line.
NOTE: Do not run a continuous burst of air, which would create positive
pressure on the fuel tank. To prevent positive pressure, do not cap
or seal the fuel cap opening in any way.
VERIFICATION METHOD:
Ensure air is exiting freely from the vent in the wing.
