Hi Butch,
The Gas Pump Collectors Guide used to be our best reference on gas pumps, but now Jack Sim's Illustrated Guide to Gas Pumps is our best book. The older guide still has lots of great photos of restored and unrestored pumps and some good info. Jack's book will have many more pumps pictured and have the values.
You can check with vendors linked on our Parts page. Click on "Parts" at the very top line of this page.
Post a photo of your pump or send me a picture to post for you. We love to see 'em. Click on the tiny postcard icon to the right of my name in my message.
