Does anybody know this? I have looked at a lot of 67 500s and I have always seen the passenger side valve cover hole being the type for a push in style grommet (round) but the grommets everyone says are the correct part number have ears on them, which is correct? Also can anyone tell me if the choke heat tube is bolted to the engine anywhere or only at the carb and manifold? Thanks a lot. Carl
I am not sure what you mean by "ears". The correct GT500 valve cover grommet is not had to find. The GT500 choke tube connects to the exhaust manifold in the same place that a regular 390 mustang would . That area is called a choke furnace. It is a place were the air is heated up and then transfered up to the automatic choke through the choke tube. It has a camber filled with steel wool like material. The choke furnace has a entrance (bottom hole) and a exit (top hole ) The different part on a GT500 is the fresh air side (bottom hole). Instead of following the choke tube up to the carb it extends up a few inchs were fresh air enters into a cylinder shaped filter with steel mesh sides . This filter keeps debris from entering the chock furnace and clogging it up. This same filter was used on many duel four setups that had a automatic choke. This item is similar in appearance to the steel mesh filter used on many pre 1966 fuel senders. The early style fuel sender filters or socks are a different length and diameter but look similar.I hope this sheds some light on the subject.
Thanks Bob, If you don't mind please let me go a little deeper on both of these subjects? I have the choke tube installed and it seems okay. My question is; aside from the carb and manifold is there some kind of bracket or something to hold it to the engine somewhere? It seems like it might vibrate if only supported at either end. And the PCV grommet...hmmmm how to explain...??? The grommet I have seen which I have been told is correct is for a "twist in" style valve cover hole (has "ears" on it), but my valve cover on that side has a round "push in" style hole.... Know what I mean? Thanks a lot, Carl
