look at the new vs. the old fuel rail / plenum seal (early style). The new one looks lot smaller than the the old one, however, the inside diameter is the same. I have called Z1 and they told me that they DID NOT send me the wrong one. He said it should be ok to install. This is a critical part of the engine so I don't want to take any chance. Any ideas... thanks alot...
