Have fuel tank off a 2007 HD that had fuel injection. Wanting to use on bike that has a carb, but petcock has to be changed, what petcock could I use that would screw into the tank.

 

Look in the Drag catalog. I think Pingel makes a petcock to do that. We did that on my friends bike a few years back. We needed a petcock with a slim insert into the tank.

 

Check Golan as well. Make sure you get the proper extension tube for the desired amount of fuel remaining when you hit Reserve. Call the Golan guy and tell him what you need to make sure you get the right fit, etc.

I have a Pingel in my EFi tank for my carb bike. You will also need an adapter for it, to match the threads - a standard Pingel part.
