Thanks for kudos on the Vid, it was my first with that cam.
I have an 1982 FJ40, my carb fan runs while I am driving, I can hear it while I'm idling sometimes. When I desmoged the rig, I made sure to keep the sensor that was attached to another piece of desmog equipment, I placed it relatively close to its original location (facing the exhaust manifold). All I can say is that I did not vapor lock on the trail and have never vapor locked, I have used low octane gas since I got the rig in mid 2009, the fan puts out plenty of air directly on the carb...don't know how well it works, but I doubt the Toyota engineers put a fan there just for visual aesthetics, they must have had some data feedback to come up with an idea of putting a carb fan. My 2 cents...
