I'm trying to install the smog pump on my all original Late 260Z (with A/C) and can't find where the adjusting arm attaches to the engine/front cover. Does anyone have any photos of the installation? I'm having crazy "vapor lock" problems and I believe if I can get the smog pump back on the engine, it will cool the engine bay just enough to stop the "vapor lock". Just for info on the "vapor lock" problem, when the engine gets up to temp, it will "burp" gas out of the carb (usually the front, but sometimes both it the weather is very hot outside) (it runs like a champ in the winter) and while the engine is at driving speed I can usually keep it running by flooring the gas pedal to clear the gas out of the engine. If the car is idling at a light it will glurp the gas out the carb, and choke the engine out. I'll have to floor the gas petal for about 20-40 seconds to clear the flood out and restart the engine. So, back to the smog pump. I think adding the cooler air into the exhaust will help lower the under hood temp just enough to stop the "Vapor Lock". So if anyone has any info or photos on installing the smog pump adjusting arm I would be greatly appreciative! ....or if you know of the problem I'm speaking of and think I'm on the wrong track, then by all means please point me in the right direction.
