Then why do some cars have it, and some cars don't? Just because it doesn't have a performance, or actual impact on the car, it can affect the driver's experience - which is a fundamental component of the 86. I consider it an issue as do many others.
They're called manufacturing tolerances. Every part has a range of dimensions. The ranges may be thousandths of an inch but sometimes that makes all the difference. When you're dealing with fuel at hundreds to thousands of PSI it can make a huge difference. That's why some have them and some don't, but they can all still meet specifications. I deal with this same type of stuff literally every day I'm at work. It can be very frustrating but machining and manufacturing are inherently imperfect because the tools that are used to do them and the people who operate them and the world they're operated in are all inherently imperfect.

I have my original fuel pump in my 2013 FRS. I occasionally get chirps but they never last. I live in California, so I get the same fuel as you do. What I've concluded from my own observation is that Ethanol doesn't cause it, or else people with E85 would be chirping all day everyday.

For my car, when I get lower than half tank, the chirps come. However, I fill up at Costco and never at other gas stations.



No failures.
I'm just starting to notice some chirping at idle on mine and it's only around ~500 miles. The gas tank is full too...so I'm not experiencing your issue with lower than half a tank of gas. Although sometimes when I drive it around a bit and stop, it wouldn't make any noise. Seems pretty random.

+1! I've heard it for the first time today in my 2015 WRB.. only have 250 miles on the car. If that's the only *issue* I need to live with, I'll hapily keep this thing for 10 years :D

I was curious if the people with 2015 WRX's would experience this problem. My understanding is the DI setup is all Subaru but I bet the fuel system is very similar to the FRS/BRZ. I guess you saved me some searching through part numbers to see if the WRX pump was the same!

No no.. I said WRB .. meaning WR Blue BRZ. Sorry to confuse you. No idea if WRX does the same thing.
