Too many.
I believe AFN is like the ALH and has the fuel temp sensor inside the pump. It is not too bad to change, but you have to pull the top cover off the pump. This is a common problem with ALH, so likely the same for AFN.

You'll need to remove the security triangle bolt, purchase a new sensor and gasket.
