This is a 6V fuel gauge that was used with the early Stewart Warner speedometer clusters. The gauge has two terminals that are upright and are seen on 1956 & 1957 gauge clusters right before 12V became a standard. These gauges have the F & E with the lines on the gauge and the orange needle. This is a New Old Stock gauge and will not be around forever so get it while you can!
Note: This gauge does not work with the early King Seely gauges with the Willys on the face.
