In my attempt to relieve the fuel pressure, I depressed the first Schrader valve I came to (passenger side). Upon further inspection I realized that this was not the fuel pressure valve, but something else, A/C maybe? Did I eff something up by doing this?

On a related note, when I did press the fuel valve, there was no release of pressure. Could this be because my truck has been sitting in the garage for 3-4 weeks without running?

Thanks for the help.
