Read TeagueAMX's post on the fuel pump. It makes sense. I just know that I am not taking any chances. That humming sound was so aggravating.
Does that mean, once you let it go below 1/4, even though afterward you tried to keep it above 1/4, the noise was present? So the key is to never let it go below 1/4, not even once?
