Fuel level indicator (5)

Ross

I believe the answer is:

gauge

(Other definitions for gauge that I've seen before include "Instrument to measure or test" , "Estimate, form judgement of" , "Measuring instrument" , "Rail track width" , "standard size" .)

I've seen this clue in The Washington Post.
