Abstract: A fluid pump includes a hollow housing, an electric motor having an armature with a commutator, a pump section rotationally coupled to the electric motor for receiving fuel at a relatively low pressure through a fuel inlet and pressurizing the fuel to a relatively high pressure, a motor brush is in electrical contact with the commutator and including a shunt wire extending therefrom, and an end cap that closes one end of the housing and defines a high pressure chamber with the housing. The end cap includes a hollow brush tower extending therefrom and defining a brush holder slidably receiving the motor brush therein such that the brush holder defines in part the high pressure chamber. The end cap also includes an aperture with the shunt wire extending therethrough such that the shunt wire is sealed with the aperture to prevent the fuel from passing therethrough.
