If harbor freight gauge is showing 65 psi at idle, is my filter in need of change? Others online have reported 65 psi as well at idle. It took about an hour last night to drop to 40 psi.
That's a great pressure, anything under 60psi is a worry with a 99+ Ford. Change the filter, if it's not known how old it is, it's time.
