Throttle Return Spring for 72-79 Bus and 80-92 Vanagon air and water boxer

This is the throttle return spring that works with the Fuel Injected Air Cooled Engine, and also the waterboxer engine.  This would be 72-79 VW Bus and 80-83 Aircooled Vanagon, and 83-92 1.9l and 2.1l waterboxer Vanagon.  It will NOT work with diesel Vanagon, or a Vanagon that has a carburetor.
