1997 Chevrolet S10 Blazer 4.3L Excessive noise from fuel rails, resonance
Posted to GM Engine on 3/9/1999

We were too busy to do anything but listen today. There is a strange resonance type noise/hum at the fuel rails by the regulator. Almost sounds like there should be a dampner between the two fuel lines. Weird thing is that the noise is much more pronounced...
