Task Instructions
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.
