Thats the wrong fuel rail adapter for the 94-04 cars. Thats for the 05+ Ford efi vehicles.
You can get the same compucar nitrous kit i have for less money it comes with a nitrous filter so you don't get crap stuck in your solenoids and have them stick open. They also have a lifetime warranty on their solenoids so you can send them back in and get new ones for just the cost of shipping if something happens to them.
