grantg,
In my 41 file drawers filled with gas pump literature the only mention of the word "handle" is when the word is used to describe the turn back mechanism for the computer.
I don't know if it is some parts of the country, or whatever, that people call what the petroleum industry called a nozzle, a handle. I hope you can see, that calling it a handle here on OG the first response will be, are you asking about the nozzle.
If you want to know a little more about nozzles go to this page of my website.
