I believe that your 4.0 has the aluminum upper intake. I am not sure that the neoprene o ring style gaskets are designed for it. if they are, the upper intake will have a groove that they fit in, and if it does have that, then that is all the gasket that it needs to seal to the fuel rail. the fuel rail to lower intake would use one of the paper/ rtv gaskets. If your upper intake is smooth with no groove in it, then use the second paper/ rtv gasket between the fuel rail and upper intake. The plastic upper intake for the 95+ years has the groove in the surface for the neoprene o -rings, my kit came with 6 of them, but you only need three. Not sure why you would need 12...Sorry to bring this awesome write up back to life. I am doing my 94 Ranger 4.0 and I am down to the lower intake now. My question is about Post #103 photograph. I have the exact same kit. However, my kit has the second identical fuel rail gasket AND the 12 neoprene seals for the bottom of the upper intake. When I removed my question upper intake it didn’t look like I had any neoprene seals installed on the bottom of the upper intake. My question is do I install the two felt pro fuel rail gaskets (one between the upper intake and the fuel rail and the other between the bottom of the fuel rail and the lower intake) and the neoprene seals for the bottom of the upper intake. Sorry for the long winded explanation (My OCD gets the best of me).
Thank you for the awesome write up!
