    injector presure leaks down

    I have a fuel presure gage and my fuel presure is at 57 when I turn the car off and in an hour or so it leaks down to nothing. Is it suppose to hold presure?

    Over an hour it will bleed down back through the fuel pump, I wouldn't be concerned unless it bled off in 5 minutes

    I have a fuel pressure guage on my fuel rail, and it does the same thing, there is nothing wrong with your system.
