Example: If your highest reading is 150 PSI then your lowest reading should be no less the 113 PSI. (113 PSI = 75% of 150PSI ) I found it in the fine print of my chilton... hard for old guys to read i know.
I know that drill too. To be more specific, I get 179-182 psi on all cylinders (302 c.i.) I'm wondering if my gauge is wacked, because it seems kinda high. I didn't disconnect the fuel pump, so I'm also
wondering if i should consider these dry or wet readings.
