A tubular body adapted to be interposed in a fuel flow line and having a passage formed longitudinally therethrough. A mid-portion of the passage within the body has a flow restrictive zone for reducing fluid pressure pulses and the tubular body includes a zone of increased cross-sectional area intermediate the inlet end of the passage and the flow restrictive zone of the passage for further reducing fluid pressure pulses. Also, one form of the invention provides a pair of spaced flow restrictive zones intermediate the inlet and outlet ends of the passage with the zone of increased cross-sectional area disposed between the pair of flow restrictive zones. Finally, each of the tubular bodies has a filter body through which fuel flowing through the tubular body must pass and a check valved air inlet for ambient air is provided and has its outlet end disposed in position subject to reduced fluid pressures in response to fuel flow through the tubular body.
