Dan Marc model number

[LJVALKYRIE]

Looking to install a Dan Marc fuel cutoff. Im reading several model numbers being used on this fuel cutoff. I'm looking for something that won't starve my bike at 70-80 for several hours. I have a big trip planned in a couple months and don't want to deal with fuel starvation out on the big road. TIA.

AFC 121?

I see where Dan Wilder puts this one on his carb racks when he builds them.



Edit:

Ordered AFC 121. Thanks
