does anyone know what thread size the threads are for the CSI on the fuel rail? What have some used to plug it, and what about the manifold, does anyone make a block off plate for that?

you can just use a AN plug for the rail. dont know of anyone that makes a block off plate for the manifold, but it isnt too hard to make one. can use the gasket as a guide.
