Abstract: A suction cover for a reciprocating pump assembly includes a plug configured to be at least partially received within an access port of a fluid cylinder of the reciprocating pump assembly. The plug includes at least one key 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. 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.
