The vanagon has a regular beetle oil  pump, and I would expect this
spring to fit.If you got lots of varnish, maybe a bottle or two of "valve
medic"( Gunk- at flaps) will open things up enough to get more pressure to
the weak points inside this old wbx. Roger

Air cooled type IV do not use the same pump as Type I / II or WBXer oil
pumps.
