Hey guys.. I went to change a fuel injector yesterday and quickly realized I needed to release the fuel pressure via the service valve (2a below). Since I've never done this before I'm wondering; Do I need a special tool? Is there some pressure hose I can buy at autozone or somewhere? Can I just press on it with a screwdriver and if I do how much pressure/gas will come out?
Thanks!

So I ended up changing the fuel injector on cylinder 1. Releasing the fuel pressure was easy using the straw from a spray can like in the video above. I just used an old tshirt to soak up the gas that came out. After removing the electrical connectors I only loosened the fuel rail on the passenger side where cylinder 1 was then lifted up the rail to get access to the fuel injector. After doing it I guess I'd advice only doing this for either cylinder 1 or 2 (the front two). If you lift up on the rail and twist it anymore you might break it so loosen the other side and take the whole thing off for any other cylinders. The benefit I saw not removing the whole thing was I didn't need to disconnect the main fuel line from the rail on the drivers side. Anyway, got everything put back together and seemed to fix my misfires on cylinder 1.
