Maybe the new ones don't? When my pump died after 200K+ miles, I replaced it with a Ford Ranger Pickup pump. (The shop I was at when it died, had one in their junk box.) I had to do some re-plumbing, but it has been working for over 2 years. -- Russ Wolfe '66 FB MT '71 FB AT '65 Bug (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
