    ok, i have 2 fuel pressure gauges. One BBK mechanical gauge on the fuel rail, and an AutoMeter Electronic Gauge in the car. The AutoMeter Gauge always shows about 5 psi lower than the BBK gauge under the hood. No matter if I disconnect the vacuum line or not. Now the BBK should be most accurate right?, But does anybody have this problem, or info about AutoMeters electronic gauges? Thanks... :shrug:
