Abstract
An auxiliary power unit includes a gearbox housing portion and a filter housing portion providing an integral housing. A filter cavity is provided in the filter housing portion. A surface circumscribes the filter cavity. A scupper includes a passage extending from the surface to an opening on an exterior surface of the integral housing. A sealing region between the scupper and the filter cavity is configured to fluidly isolate the scupper and the fuel filter cavity from one another. In one example, the filter cavity receives a fuel filter cartridge. A cap is secured to the filter housing portion and encloses the filter cavity when in a secured position.
