A press fit plug assembly used to seal a fuel rail in which a pressure pulsation damper is inserted. The fuel rail includes an elongated member, a first member, and a second member. The elongated member extends along a longitudinal axis, the first member being positioned within the elongated member, with at least one inward projection extending toward the longitudinal axis. The second member, positioned within the first member, has at least one outward projection extending away from the longitudinal axis. The outward projection engages the inward projection between the first member end and the inward projection. A method of assembling a pressure pulsation damper within a passage of a fuel rail is achieved by forming a first seal between the fuel rail and a first member; inserting the pressure pulsation damper through the first member; and forming a second seal between the first member and a second member.
