A combustor or augmentor of a gas turbine engine is provided. The combustor or augmentor includes a wall defining apertures and an interior having an inlet, an outlet and a mixing region between the inlet and the outlet and fuel injectors. The fuel injectors are respectively arrayed along the wall at corresponding apertures to inject fuel into the mixing region. Each fuel injector includes a fuel injector body defining an injection outlet through which fuel exits the fuel injector body toward the mixing region and a pintle. The pintle includes a first end, a second end and a pintle body extending between the first and second ends. At least one of the first and second ends is attachable to the fuel injector body to position the pintle body between the injection outlet and the mixing region.
