Speedwagon Posted July 6, 2011 Share Posted July 6, 2011 When I did the SPFI conversion on the Brat, I took the pump from the donor car. Everything was fine, though it did make some noise. One day it quit making noise(and just quit), so I put in an F150 pump. After a day of use, the pump got very loud. After a few days of this, I figured the pump was going bad, so I exchanged it for another pump. Same thing, after a day or so of use, the pump is making a horribly loud noise. So what's the deal here? There has to be something with my car that is making this happen. I do notice that the noise will change in pitch, in time with the turn signals if one is on. Does the noise come back to some kind of electrical problem somewhere? Link to comment Share on other sites More sharing options...
