10. Slowly open the instruction lockdown valve jackscrew on the fuel tank solenoid valve of the fuel tank to be 

vented.  

11. Observe the gauge pressure of the Fuel Filler Neck Venting Kit. The pressure should be at tank pressure 

if the fuel tank solenoid valve was identified as, "stuck open".  

12. Slowly open the bleed valve on the venting kit and allow the contents of the fuel tank to vent to the 

atmosphere. Venting can take in excess of one hour.  

13. Close the bleed valve on the venting kit, and observe the gauge pressure. The pressure should be at or 

near 0 kPa (0 psi).  

14. Remove the fuel tank solenoid instruction lockdown valve.
