John,

The diameter on the air injection pump on my 1979 Silver Wraith II is 4.5 inches. It is a US spec car. The pulley thickness around the circumference is 9/16" and the belt width is 7/16".

Many thanks! I bought a genuine parts belt and it was too big. The only thing I could think of was that the pulley was the wrong size...
