1. A high-pressure fuel pump configured to couple to a low-pressure fuel pump, the high-pressure fuel pump comprising:
a body that has a forward end and a rearward end opposite the forward end, the rearward end protruding from the body including a press zone and configured to couple to the low-pressure fuel pump; and
an embossment formed over the press zone that includes at least one fastener boss configured to receive a fastener to couple the low-pressure fuel pump to the high-pressure fuel pump and that is formed at the rearward end of the body such that thermal stresses that cause geometrical deformations at the embossment are reduced through a range of engine temperature operating conditions.
