Did all 77 FJ 40 come factory equipped with a insulator between the base of the carb and the intake? Looking at SOR diagram, there's a base gasket sitting on top of the insulator that's only available thru Toyota if you purchase the insulator $100.00 plus (includes insulatorand gasket). Then there's a plenum gasket that sits under the insulator. It looks like both gaskets are available individually from SOR. I assume that the insulator is for reducing vapor lock. Does everybody use this insulator and gasket set up?
