Got the gauge hooked up when i got home, good thing we got some cummins parts at work, made a fitting to replace the banjo fitting and schrader valve and hooked in there, went and changed the fuel filter since i dont when it was changed last had 13 psi at idle and 8 psi wide open throttle going up hill, i am guessing that is close to normal for a stock engine.
thanks for all reply's
