) Depending on the configuration you choose to set up your GFB valve (vent-to-atmosphere or plumb back), ensure the factory recirc hose that returns vented air to the intake is either plugged, or connected to your GFB valve’s outlet – do NOT leave it open to the atmosphere. Various sized plugs and plumb back outlets are also available if required. 4) Connect the vacuum nipple on the top of the GFB valve to the inlet manifold AFTER the throttle body (see schematic engine diagram).
Maintenance GFB products are designed and manufactured in a way that, in most circumstances, requires little or no regular maintenance. Cleaning and/or disassembly are only necessary if the piston does not move smoothly or if there is damage from dirt or other foreign objects.
