Re: Cranbrook Pre-Build Mockup and Advice
I have the tank from Imperial Cycles and they ship it with the cap, petcock, and mounting adapter. The adapter snaps over your top bar and is secured with a small screw. Then you put the tank over it and put the bolts through. I added in some rubber gasket material on the back to help prevent vibration. It's a great little tank and holds a little over 3/4 gallon. I have an older AMF frame so i'm not sure about the one you are talking about. My engine came from zoom bicycles. Good luck with the build!
