Fuel Pressure
My Ford is 2001 F150 4.6L V8.
One thing I noted while cleaning the injectors; I read that the fuel rails (schrader valve) needed to be depressurized. I was expecting a geyser from what I'd read, but it was a nonevent.
Is this normal? Does it bleed off if you wait for the engine to cool down?

If you depressed this valve long after running this, or turning the key to the on position, ( like 4-8 hrs) then you might get a "non-event".
You might want to get the fuel pressure tested to be an the safe side.
