Carter fuel pump was nice and quiet for the first week of install, started making an intermittent sound today. Any ideas? I've already got a warranty replacement coming but would be nice to have a theory of what happened, or if it was possibly install related. If I touch the fuel hose I can feel vibration when it makes the noise.


If the part is bad it doesn't fill me with confidence about the replacement, either.
