A fuel pressure damper (10) includes a housing (15) defining an inlet (46) constructed and arranged to receive fuel. An orifice disc (54) is provided at the inlet and includes at least one orifice (58). A cover (22) is coupled to the housing. A flexible diaphragm (12) has a periphery fixedly secured to at least the housing or the cover and has a freely movable central portion (36). A compression spring (14) biases the diaphragm to a normal position. In an operating position, the central portion of the diaphragm alone, or in combination with the spring, is constructed and arranged to dampen fuel pressure pulsations at the inlet. The orifice is constructed and arranged to ensure that pressure pulsations of a certain magnitude are prevented from entering the damper and damaging the diaphragm.
