Injector insulator question on 1990 300zx N/A

[big dawg]

I have been having a discussion with other Z owners about the little injector insulator that fits into the injector hold down bracket.This insulator is made of rubber with a metal plate, of the same shape, fused to one side.Some say that the rubber side of this insulator should face (be touching) the injector when you screw the bracket back on top of the injector. Others say that the metal part of the insulator should face (be touching) the injector when you screw the bracket back on top of the injector.Which is the correct way???

it really does not matter, I believe I out mine metal side up, IIRC

yeah mine are metal side out also, thats the way they were designed and thats the way they need to be.

"yeah mine are metal side out also, thats the way they were designed and thats the way they need to be."

So to be clear...if I understand, you are saying that the metal side of the injector insulator should face away from the injector and toward the hold down plate (be touching the hold down plate) and the rubber side should face toward the injector. Correct?
