1. A suction cover for a reciprocating pump assembly, said suction cover comprising:
a plug configured to be at least partially received within an access port of a fluid cylinder of the reciprocating pump assembly, the plug comprising at least one key that includes at least one protrusion, and at least one recess, wherein the at least one protrusion extends radially outward from an exterior surface of the plug and defines a pair of lateral sidewalls, a proximal sidewall, and a distal sidewall, and the at least one recess is defined on the exterior surface of the plug between the lateral sidewalls,
the at least one key being configured to be received through a keyhole of the access port such that the at least one key extends within a keyway of the access port when the plug is at least partially received within the access port, wherein the plug is configured to be rotated within the access port between an unlocked position wherein the at least one key is aligned with the keyhole and a locked position that prevents the plug from backing out of the access port.
