The red Z06 fuel rail covers will need to be cut for the fuel lines to fit. The ones I have on my car are specifically from a 97 Corvette so they were precut for both fuel lines. Only draw back on the 97's is they cannot be ordered in red. So to make yours work, you will need to cut a slit in them twoards the rear of the drivers side cover. Just make it identical to the one thats already there and you'll be good to go.
