 Has anyone encountered a similar problem on the 320?
 
 Since installing my new gauge I've noticed it doesn't always build to full
pressure and thus the nose gear door doesn't close when the gear is first
retracted. Dropping and raising the gear allows it to function normally. Would
cracking the valve after start up help I wonder?
