Lots of folks have made a bracket that attaches it to the engine either near the spider or down by the throttle body. I chose a different route and didn't mount it to a bracket at all. I simply suspended it via the fuel line from the mechanical fuel pump to the throttle body and then covered it in a length of large fire sleeve that ACS sells for this very purpose. This is a method that was spelled out in the install instructions for another item that is made by EI that connects to the FT60--No issues in 170 hrs.
