Actually, the Fortran support is amazingly good. The implementation of f2py is very well done that very little is needed to be done by the user. It just works. However, there are some gotchas one has to be careful with older code - need to have !f90 for example in the first line. Also you need to make sure inputs and outputs are clearly identified with cf2py intent(in) var1,..varn and cf2py intent(out) var2....
