Re: [DML] fuel pressure tester

["Dave Sontos" <dsontos@xxxx>]

Ok, I had to pull out my book to refresh my memory. With the valve open at
50 degrees F. the Control Pressure readings should be around 23 psi., at 75
degrees F. the pressure is 35 psi. Now close the valve and the pressure
should jump to 65-77 psi. This is the System Pressure. Open the valve and
reconnect the electrical connections and start the engine and allow to warm
up As the engine warms the control pressure will move to about 51-57 psi.
Now shutoff the engine and watch the pressure, it should stabilize around
25-35 psi and stay there at least for twenty minutes.
