Fuel Quantity Indicator, Main Tanks, P-38 Lightning, GE 8DJ12LAE
Here is a fine specimen of a Fuel Quantity Indicator for the Main fuel tanks as used in versions of the infamous US Army Air Force twin-tailed fighter P-38 Lightning, made by General Electric, Model 8DJ12LAE, as confirmed in the P-38L Erection and Maintenance Manual dated 1945.
The P-38 had two fuel quantity indicators.. this was for the main tanks, each holding 0-60 gals. The indicator has two pointers (the second one is barely visible in the photo as it rests behind the other) one for each tank. We know of no other aircraft that used this fuel indicator.
It is experienced but is in fine condition for its age. Measures 2.25 inches diameter by ~3 inches deep.
