IIRC, a few '68-69's came with them. But I don't remeber why. It may have been like on automatics only. > >One thing that I DO know - my car is very hard to > >restart once its been warmed up.

My '71 does this once in a while on real hot days. I think, and this is just my opinion, that there may some kind of fuel vaporization going on when the engine is at high temperature. By turning the key off and on, you are running your pump each time, and pushing the vapor out of the system. > -- 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
