The replacement of a fuel measuring stick on a McDonnell Douglas aircraft is quite easy. Best of all...... it's completely dry.
The stick sits inside a sealed tube. The magnet on the tip of the stick is acted upon by a float that rides up/down around the tube.
Replacement of the stick takes less than five minutes.
A simple snap ring holds the assembly in place. A pocket screwdriver was all that was needed to snap this ring in.
