1. A fluid end section, comprising:
a housing, comprising:
a longitudinal axis;
a first surface; and
a second surface;
in which the first and the second surfaces are joined by an outer intermediate surface;
a first bore extending along the longitudinal axis of the housing, the first bore interconnecting the first and second surfaces;
a discharge bore interconnecting the first bore with the outer intermediate surface;
an upper intake bore interconnecting the first bore with the outer intermediate surface;
a lower intake bore interconnecting the first bore with the outer intermediate surface;
a stuffing box secured to the second surface of the housing by a plurality of fasteners; in which the stuffing box comprises a first portion having a first outer diameter and a second portion having a second outer diameter, in which the second outer diameter is larger than the first outer diameter, in which the first portion is situated within the first bore; and
