YES, and congrats but to admit had expected a bit more "aerodynamic" solution similar to the J-10 or the French Mirage series ... but not only such a simple "tube out of the fuselage-design" !
Anyway if it works properly ...

I think it is probably a temporary design. They needed to refit an "old" frame where they added the IFR as simple as possible. Here you have a direct connection to the existing main internal fueltanks. Maybe they add a pipe through the fuselage (in block 2) so they can add the same as J10 IFR.
What is strange is:
The PAF Mirages have the Israeli IFR...
The JF17 has the Cheetah IFR...
