Did the S2 fuel pump swap and I'm getting a high-pitch whine from the pump area. I used a brand-new OEM pump. Assuming this is not normal. I clocked the pump to approximately 2:00 so the outlet pipe wasn't binding and everything is nice and snug. Before I take it apart, what should I be looking for to correct?

Just because its a new pump doesn't mean the pump itself is good sadly. I would remove the pump and apply power to it on the bench to see if the pump itself is loud with no strain. If its loud on the bench, I would warranty it out.

Great advice. I'll look into bench testing and try to pull it once the tank gets low again.

Yes. Because this is not relevant to the actual swap thread.

Keep us updated on what you find out. Did you purchase the pump from a Mazda dealer?
