mantadoc Posted February 14, 2010 Share Posted February 14, 2010 Damper Diaphragm (Fuel Pump Assy.) GM 90019987 Car manufacturers would make more profit if these were not fitted if they do nothing. However, never noticed any bad effects running without. Quote Link to comment Share on other sites More sharing options...
