What should be the fuel pressure on a 1989 s10. Also should you check the pressure in front of the filter or behind underneath the truck. And what should it be running

I've read somewhere that it should be 9-13. But didn't say anything about running if it's running should it still be the same. And while cranking should it drop or stay.
