So I took my car out for a spring shakedown cruise last week. I ran it for a few hours with ac on which of course blows hot air on the fuel pump area. After getting home the pump was singing a song of woe. The engine ran fine. So, is the pump on it's way out when it makes noise or is this a normal symptom of a pump that just got too hot? Keep in mind it was very hot that day and the engine still ran fine. I have a spare pump I can replace with or shall I get a hot air dam? Or both?
OE pump btw, not the new ones. Not sold on those quite yet.
