Read accurately in a T210L. No modifications needed. Invaluable device whether you fly with full, full or partial tanks. If you ever fueled a 210, then you know how deceiving the fuel level can be. This is an essential device for confirming the fuel level. I use it before every flight.

Exactly as advertised, works great.

Works perfect and small enough that it is convenient to carry in the aircraft.

Worked perfectly on my 1976 T210L- calibration checked, Well worth the money if you fly with partial fuel.
