Ab initio calculations of QED radiative corrections to the $^2P_{1/2}$ -$^2P_{3/2}$ fine-structure transition energy are performed for selected F-likeions. These calculations are nonperturbative in $\alpha Z$ and include allfirst-order and many-electron second-order effects in $\alpha$. When comparedto approximate QED computations, a notable discrepancy is found especially forF-like uranium for which the predicted self-energy contributions even differ insign. Moreover, all deviations between theory and experiment for the$^2P_{1/2}$ - $^2P_{3/2}$ fine-structure energies of F-like ions, reportedrecently by Li et al., Phys. Rev. A 98, 020502(R) (2018), are resolved if theirhighly accurate, non-QED fine-structure values are combined with the QEDcorrections ab initially evaluated here.
