connect the fuel pressure gauge to your fuel rail ( port ). It looks like the same port you have on your tires, its near the front of the intake. start the car check the gauge and see what your fuel pressures at, then pull the vac line to your fuel pressure reg and again check to see what your fuel pressures at
