The valve is on the passenger side fuel rail. It's about where the the cowl starts. It looks like a little straw coming off the top of hte fuel rail. A Schreader valve is the same type as on tires. In this case, just unscrew the cap. Then there's this little piece of rubber to pull off - or it may come off with the cap. Finally, with a rag around/over the valve, press the pin in the middle. I used an Allen wrench to press the pin.
