Abstract: In their paper, Injektoren endlicher auflösbarer Gruppen, Fischer, Gaschütz and Hartley ask the following question. If $ \mathfrak{F}$ is a normal subgroup closed class of groups and if $ G$ is a finite solvable group which possesses $ \mathfrak{F}$-injectors, is it true that any two $ \mathfrak{F}$-injectors of $ G$ are conjugate in $ G$? A partial answer is given. It is proven that if $ G$ has $ p$-length 1 for each prime $ p$, then the answer to this question is yes.
