Fuel Pump Pressure???

On another site, someone stated that the psi on the schrader valve when the engine being turned over should be 40 lbs. Does this sound right? Mine is 25.

Thanks

The 25 was on cranking only, not running.

Are you having problems starting or have you checked it running?

The factory diagnostic chart says => 20 PSI at cranking RPM is acceptable.

The same reference also states 30-70 PSI on the road at WOT. I'm pretty sure most of us shoot for the higher end of this spec.
