The early injectors did not have that, and had the injector pin exposed. I would put it in and see if it is OK, if not, put in one of your new ones, or the whole set. BTW, if you need to store used injectors, store them in a jar of kerosene. It will keep them for rusting or sticking. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) '05 KIA Sorento SUV russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
